Oh, this isn't related to psychosis, but it has to do with dissociation.

I had no idea what dissociation was, I had never heard of it, until it happened to me.

I was flying to Hawaii and for the first few days I had really intense depersonalization and some derealization. It scared the **** out of me. I couldn't figure out what was wrong.

It wasn't until I returned from the trip that I had a chance to look it up. When I found out it could be brought on by jetlag I was sooo relieved.
