Hello just1: I noticed this is your first post here on PC. So... welcome to PsychCentral! I'm sorry I'm not able to offer anything in the way of an explanation for what you experienced. Hopefully some other members, here on PC, who are more knowledgeable than I will yet reply to your post.

What this sounds like to me is something that might possibly fall under the heading of dissociative disorders. There's a forum, here on PC, dedicated to this topic. Here's a link:

The other forum that may be applicable, I suppose, would be the psychosis forum:

Here's a link to an article, from PsychCentral's archives, that offers definitions for the terms psychosis, hallucinations & delusions:

And then here are links to 3 articles on dissociative disorders:
