I'm 16 years old and ever since I was about 5 or 6 I would have hallucinations about twice a year. I noticed that it commonly happens when I'm really hot and sweating or when I have a fever.
The hallucinations are about very random things. My most recent one was when I woke up and I saw a tall dark figure walk quickly past the door. A few minutes later (still in the hallucination state) I walked downstairs with my blanket and put it on a chair. Next, I walked back upstairs (still in the hallucination state), layed in my bed, and I thought "where did the blanket go?". Then I started searching all over for it. I then thought "maybe I left it downstairs". Then I went downstairs to look for it. I found it, went back upstairs, and layed in my bed. Finally I was out of the hallucination state. This happened late last year.
Another was when all I heard was voices. The voices were of my friend's and it sounded like they were playing some sport and arguing over something. Like I said, the hallucinations are very random.
My question is why the heck am I hallucinating and is it something I should be worried about. I think one reason could be because of sleep deprivation because I definitely don't get as much sleep as I should. Any thoughts? Thanks for anyone's help.
