So in theory if you stop sleeping for a week and then sleep for a straight two or three days then your last REM period should be about 6 hours.

But like matte mentioned, would you even be able to remember your dreams if your THAT sleep deprived?
I'm pretty sure the effects do not stack that way.

From what I understand, generally when you skip sleep, you lose it. For example, let's say you normally sleep 7 hours a night but you decide to skip a nights sleep, and even the next nights sleep for some reason. You wouldn't sleep 21 hours the third night though when you went back to bed (3 x 7 hours of sleep). You'd most likely sleep 14 hours give or take.

That being said, I'm sure your REM sleep would increase, but I'm quite positive it doesn't carry over from the nights you've missed.
