As far as psychotic symptoms, I get paranoia, voices, visual hallucinations, and a lot of delusions. I also get nasty headaches to accompany these symptoms, sometimes. Over the last ten days I thought 3 times that I was God. No idea what causes these ideas; it wasn't like I was reading a book about religion or something. Last year I was reading books about geniuses, and sure enough, I started believing I was a genius

I'm not a pdoc, but I think that hallucinations are psychotic symptoms. The intensity of the symptoms vary in different people, both over time and with each episode, and there are triggers which make them worse. Your sensation of someone pressing down on your body would be really creepy. I've not experienced anything like that, that I can remember.

I have voices trying to convince me to kill myself, from time to time, so I get where you're coming from. Nasty voices, no good, and you have to fight them off, or grit and grin. Glad to hear you have a therapist; make good use of him or her.
