It may be a psychotic episode, it may be mania manifesting itself. Who knows? My T always talks about how the brain is so awesome in how it will attempt to regulate and balance itself. If there is a negative entity, it would make sense for you to have an experience with a positive entity. That's what I think . . .but what do I know? I think it is cool that the bipolar brain can experience things that other people can't experience. Their lives must be boring.
