Dream or nightmares...

Yesterday, I only got about 1 hour of sleep before work. Biked to, and from, work...then collapsed into bed when I got home.

I slept for about 4 hours and had a very peculiar dream. The kind of dream that is so vivid and real, that when you wake up, you don't recognize where you are. I'll even go 1 better, I didn't immediately recognize who I was, either. I stretched out as I awoke, and felt crammed into a different container, then had a brief spaz. Funny thing is, this isn't the first time I've had dreams like this. I've had them frequently enough, that I sometimes wonder which side is the "reality" (note the quotation marks).

I don't remember the exact details of the dream, I just remember that I wasn't my waking self. I was someone else, somewhere else, doing something else. And it felt more real to me than things feel now.
