I found this interesting article about "thoughts": What Is a Thought? | Psychology Today

I'm sorry you're still struggling with psychotic thoughts, bpcyclist. Though this may not sound that comforting, I'm a believer that such symptoms can and do resolve themselves, at least a bit, over time.

There was a famous man from my area who developed schizophrenia as a university student. You probably even know who he was. His psychosis was predominately auditory hallucinations. From what I read, there came a time when he had insight enough into them that he could choose to actively ignore them. Not let them take him over. He lived a long life doing this. Perhaps it wasn't ideal, but his ability to tolerate did free him, a lot. I guess it's similar to how we adjust to other hardships in life, such as medication side effects, maybe pain tolerance, grief, etc. For many, I think this manipulation can be fully healing, over time. Also, the practice of the choice can eventually make what still exists, seem not to. Work it away, or wish it away, for long enough, and it disappears or fades. This is basically manipulation of thoughts. Those mysterious thoughts.

Of course I know wishing away issues sounds hokey, but then why does it happen for certain people? How is it that there are cases where tumors seem to miraculously disappear?
