Wow, this is apparently so common. One of the worst dreams you could have. Although, I do like those dreams-within-dreams. They usually happen when I'm "resting my eyes for five minutes". I dream that I've awoken and am dutifully completing my tasks for the day. Do you get those?
I don't often get those, though I did once have a dream-within-a-dream combined with sleep paralysis that was like seven dreams deep.
I took a nap on the couch. Woke up on the couch, could not move. Woke up on the couch, could wiggle my fingers. Woke up on the couch, tried to roll over but woke up on the couch. Managed to roll off the couch onto the floor, but woke up on the couch. This continued til I managed to roll off and drag myself about a foot with my arms (my legs were still paralyzed), then I finally woke up on the couch, my whole body tingling, and wasn't sure I was really awake until I'd gotten up and gone about the rest of my day.
I dunno, maybe everything since then has been a dream and I never did wake up from that nap.
