I have something similar to what some people are talking about on this subject. (An example of mine is:) I will be walking down the street by myself (or someone might be with me), when all of a sudden...i feel like i am in a dream and i am not actually walking, its all just a dream. I can get extremely paranoid when this happens. But it only lasts between 2 and 10 seconds. Then i will be right back in reality. Its been happening almost everyday for the past 3 months. For those out there who use or have tried marijuana, and have had a bad trip (where you don't know if you are dreaming or awake and you can paranoid), that is EXACTLY the feeling i get. And its only been happening since the last bad marijuana trip i've had. I'm trying to understand what it could be. I think it might be my mind having a placebo effect that i am under the influence of marijuana when i really am not. That is the only real explanation i can get out of it. I've talked to my friends about it, and they said they have never experienced this. If anyone knows ANYTHING about what could be wrong with me, or you have an idea, please reply back to this. I really need someones help. Thank you.
