Called hypnagogia, your experience is common and usually occurs as we transition into sleep or from sleep to wakefulness. This experience can involve both sound and visual imagery that incorporates sensory elements of our sleep or resting environment. Elements such as a clock alarm, door knocks, and hearing someone calling are examples of sleep environment influences that frequently become part of what an individual at rest perceives amid hypnagogic experiences.

Ah, wunderbar! Thanks McDreamy

Hello everyone

It happens quite often that, since I wake up at 5 a.m., I tend to rest my eyelids on my train rides.

I'm never really asleep. I hear everything that happens around me and I am aware of my whereabouts.

However, it so happens that certain dream-like thoughts tend to come up in my mind, and when 'in' these thoughts, I tend to build further on them and believe them. I cannot give an example straightaway (perhaps tomorrow, if it happens and I remember it in the evening).

These thoughts can come up really fast, after even 1 or 2 minutes of eye closure and they are comparable with a state of sleep in which you are still in a more conscious state and able to wake up on your own command, starting to have strange, illogical, abstract thoughts.

It's like dreaming without image, and with the possibility of exiting it consciously: when these thoughts happen, I can fully awarely 'wake up' (although this term would not be correct since I'm strictly seen not sleeping) and think "the hell were you thinking, stop it".

Is this a genuine sleep stadium? What causes these abstract, illogical thoughts? Is it possible and logical for this stadium to happen much faster on a moving vehicle when being really tired than in your own bed? And why doesn't this stadium evolve into a real sleep, contrary to sleeping in my own bed?

I know it's a bit vaguely described, but I sincerely hope others here experience comparable things when 'sleeping' in vehicles. I know of at least one other person. Out of one (he's the only one I happend to talk about it with).

Thanks to anyone acknowledging this phenomenon and doing an effort in describing and explaining it.

-F.

NDEs are considered fringe science, so you won't find any irrefutable studies on this topic. You'd fair better with source exploring the effects and treatment of Post Traumatic Stress Disorder (PTSD). Whether or not you believe negative NDEs are essentially nightmares, you will find that PTSD studies and research addresses concerns like yours. PTSD, as you may know, involves the continual, iterative psychological effects of traumatic and stressful experiences. You appear to have extreme anxiety and fear regarding a traumatic experience you have never had, which may have roots in prior trauma. It's clear from your responses that no amount of legitimate research contrary to your fears and concerns will alleviate those issues. I agree, as you have previously conceded, these issues should remain in the hands of your therapist.

Belgian neurologist from Liège, Prof. Steven Laureys, has recently published valuable information on NDEs. You guys might want to look into it.

'96 FTW

0/0 can be anything.

like:

0*2 = 0

i.e: 0/0 = 2.

 

Now:

0*x = 0 or 0/0 = X, where x can take any damn value.

I'm not convinced that that is true. But I generally don't feel the need to go into discussion with someone from India when it comes to maths.

Nightmares are likely more intense than NDE because nightmares generally don't involve a brain in aerobic and metabolic distress. A dying brain secretes a series of neurochemicals (dopamine and endorphins) that produce soothing and euphoric effects. This doesn't happen during nightmares because the dreaming brain isn't actively engaged in life sustaining efforts. Soothing and euphoria inducing brain chemistry produced near-death emphasizes a low-intensity distinction in NDEs from nightmares.

Dying brain be like: ahhhhh, what a happy place to be with friends

Nightmare brain be like: sh*t bruv, I'm sorry but I can't handle this, you're gonna have to solve this one yourself, sorry mate, good luck, bye!

How about instead of criticizing me, someone actually gives an answer to my question?

Just answering questions on the homework help part of the forums is just not how things work here.

And I'm flattered, but no, I am not brilliant.

EDIT: oops, it's not even in the homework help section.

If you don't care to understand physiology, you won't. It's such a beautiful discipline, but requires great interest in it to be fully understood.

Ergo, I'm not sure if I can be much of a help here, since I'm not sure my help will 'arrive good', or be appreciated to the extent it is supposed to.

There obviously should be some good information in (I own these books)

• Ganong's Review of Medical Physiology (24th ed.)
• Kandel et al.'s Principles of Neural Science (5th ed.), not sure there is information on glucose metabolism, but it'd astonish me if there weren't information on glucose consumption in the CNS
• Lodish et al.'s Molecular Cell Biology (7th ed.)

Have you got an idea of the meaning of hydrostatic and osmotic pressure?

You keep astonishing me, btw ... Never seen a chemist abbreviating mercury as HG instead of Hg

What I find intriguing is that after some dreams (read: nightmares), I am very relieved and happy when waking up, realizing that it was just a dream.

But rarely, I find myself in an impossible situation to put it in perspective, not fully consciously knowing that it is over, and the emotions reside in their full intensity in my brains for some minutes, leaving me 'emotionally blocked' and with an incompetence of overcoming these emotions with reason.

Can cancel out because x/x=1.

[math]\Leftrightarrow x\neq 0[/math]

And in no other case. And since [math]x=1-1=0[/math], it is false.

There is no such things as "not an exact" maths.

It is false to cancel out (1-1)/(1-1) as that is, undeniably, the same as 0/0

My own experience is that emotions in dreams are much more intense and fearsome than when awake; it's like everything is turned up full volume. There is no tempering of them, like in waking life.

Yes, indeed. In a wakeful state you can also put things in perspective and approximate them rather rationally. In dreams, you are fully subjected to your strongest emotions.

Right...

Well, there can be another method-

0/0=1^2-1^2/1-1=(1+1)(1-1)/1-1=2

There is so much so wrong with this.

For the record: 1² - 1²/1 - 1 = -1

So you say 0/0 = -1

Which is very obviously false and since you have not proven this in a lemma before, it is incorrect to use this in your proof.

You seem to have a little problem using parentheses.

You also state that (1+1)(1-1)/1-1 = 2

Let's continue with what it says: (1+1)(1-1)/1 - 1 = 2

2 * 0/1 - 1 = 2

-1 = 2

Obviously false.

Let's continue with what I think you mean:

(1+1)(1-1)/(1-1) = 2

(1+1)(0)/(0) = 2

2 * 0/0 = 2

Which you cannot use since you try to prove that 0/0 = 2, and now it states that 2 * 0/0 = 2. Such thing can never be true. As stated before, 0/0 is undefined and will never be.

Hi, I'm new in this forum.

Hope to learn many things...

Start by eradicating theorems that are, for very obvious reasons, wrong, from your mind. (Yes, I am referring to your "Prove it" thread)

Besides that, feel welcome.

This thread frustrates me more than a thread is supposed to for various reasons.

I've occasionally had dreams in which I was subjected to the most cruel happenings and experiences one can discover. I can't deny having woken up once in a blue moon, crying about what happened in my dream, still influenced heavily by the emotions still persisting from those dreams. Our limbic system is very interesting, isn't it?

But the opposite has - luckily enough - occured to me too, and much more. I pity people not dreaming. It seems terrible to me not to have those experiences. Even the bad ones, keeps you ... probably not sane, specifically, but idk, I feel like I wouldn't enjoy sleeping as much if it weren't for the dreams.

Seizure alert dogs; do you mean dogs trained to see a seizure coming by certain factors? If so, I have 2 problems with this specifically, and a practical problem:

• I'm not sure every patient has 'prodromen' when it comes to seizures
• When a patient does have prodromen before a seizure, he will most likely know he's about to have a seizure himself, and doesn't need to have a dog sensing those prodromen to tell him or other persons. When a patient does not have prodromen, he won't see it coming. In those cases, I'm clueless about how you could train dogs in sensing imperceptible changes in humans announcing a seizure.
• Practical problem: it's quite useless? Experiencing a seizure is not immediatly a medical emergency, most of the time helping the patient consists of just putting near objects away, avoiding him to hurt himself; there is no way whatsoever to stop the seizure as a bystander. And that could result from the alert a dog would give you: you could only sit and wait for the seizure, putting the anxious patient away from objects
• Possible solution: if there are dogs that do sense certain prodromen of seizures (but only then, when a seizure is happening, it is, as stated above, quite useless, and is also useless before the seizure when not considering this point), patients with deep brain stimulators or vagus nerve stimulators may want to activate their stimulator, or potentiate (increase) its operation, hoping that that might just inhibit, or impede, the genesis of the seizure

That diabetes dog thing is very interesting indeed. Could you share a more scientifical source?

I endorse these ideas.

Function will butt in then, hopefully. Thanks for the link.

Someone called?

Tbh, I had to quit the brachial plexus research due to health reasons (mononucleosis), but I'll try to help where possible.

Blah blah medical disclaimer (I'm not a doctor, do not consider me as one and do not blindly follow my advices; when in doubt, consult a physician).

My intuition tells me that a nerve problem (i.e. compression) would rather cause pain than numbness - though I just read about handlebar injury.

Can you try to explain where exactly in your hand the numbness appears? Does it stop immediately when you stop cycling? Or does it go on for a (short) while? Is it preceded by pain? Or straight away numbness? Have you experienced sharp pains in your hand during the cycling, or when doing any other activity? Do your symptoms appear in any other situation?

--

Something else that comes to mind: I've discovered that when I lay down, supporting my body on my forearms, my hands start to feel numb, and indeed, a complete absence of pulse: probably compression of subclavian/axillary artery.

But that doesn't mean that is the case for you: it may very have a neurological cause (that is, caused by a nerve; I don't mean CNS neurology). Compression of that artery is a common symptom in thoracic outlet syndrome (TOS), in which, by the way, also the brachial plexus may be compressed.

I'd like you to test something out: after these few miles, when the numbness appears, try to stay in the same position, so to keep the numbness present; then, very carefully, relieve 1 arm of its supportive function (i.e. release the handlebar), and with that hand, try to palpate your ulnar and radial arteries of the other arm. Again: very carefully. In best case, you will have 1 non-numb arm being able to do everything (palpating), and 1 numb arm undergoing your examination.

If you don't feel a pulse, you may want to be tested for TOS

You've already elliminated the possibility that you're nuts and it's coincidence.

Why so? I'm not keen to call people "nuts" (rather than calling them susceptible to having and expressing disrupted thought patterns), but let's focus on that last one: why has your character ruled out the possibility of being it a set of randomly arranged events?

It is rather unnerving to buy something off Amazon.say, then see adverts advertising the very things you've bought on a banner in SFN! I know how to stop it but I can't be bothered anymore..

Tbh, cookies have given me lots of thoughts of "oh that's beautiful, might buy it someday" after I visited an online webshop, and I can't say I don't like it

Let's just be honest: big chance that what you say of us, we think of you. We might express the same thoughts about you as you have on us, which is why discussing anything here remains pointless. Even if we remain objective (sorry, I'm usually not someone approving a we-you-seperation, but you leave me no other choice), you're not giving us the chance to come with arguments that you are blind to.

However, I'm not spending any more energy in upsetting myself by giving you any more thoughts.

I suggest you seek professional help, such as StringJunky suggested (perhaps a bit mockingly, but I personally can't blame him after your rage), and I suggest that this topic be locked: OP is blind for any input, is and remains blind to evidence-based stuff, denying the thoughts about the possibility of having and expressing thought patterns which are quite disturbed and disturbing themselves, failing to see potentially valuable inputs, let alone to cope with them, imo forming a threat to extremely susceptible (alas, naive) members and guests visiting these forums, triggering useless paranoia.

Let's close the debates and wait for an official intervention here. This topic is hopelessly lost and input, of any kind, will not bring us any further.

My curiosity is aroused and bursting, so forgive me for asking: what do you do for a living, Badstuffhere?
