you can get into psychosis by dwelling too much on one thing for too long... well at least I can that is how it starts to happen for me the delusions and hallucinations. Best to think about lots of things read, a book watch tv, go for a walk. DO NOT BE ALONE WITH YOUR OWN THOUGHTS. My Dr. said that is how mood disorders become mixed into the thought realm of pychosis and that is what always happens to me. Not fun not fun at all. Has taken me 6 weeks to get out of it this time and I was there for 5-6 months... strange world.
