My own experience was very spiritually based. At the time I felt extremely powerful and magical. I don't feel that way any more to the extent that I did then. I still believe in energy and magic and angels and demons etc. etc. But I now see it differently that I did at the time. It's hard to explain. Sometimes, though, I miss that all powerful feeling.

My MIL has a very, very religious and spiritual psychosis with God and demons, etc. She has 0 insight that it is psychosis. But, she has her faith which is powerful and positive for her, then tangled up with it is this delusion and hallucinations, which to her are 100% real. She led a very traumatized life from early childhood with a lot of abuse, along with a lot of pretty major health problems. Her first psychotic/manic episode was when she was in her mid-30s and I wouldn't be surprised at all to learn it was trauma induced. However, mental illness runs really strong in her family. Her mom, brother, and my husband and his brother all have different types of MI. So, trauma + biology = bipolar with psychosis.
