Is it true that...?

REM periods are more frequent during afternoon naps or that you enter REM quickly when napping in the afternoon? I feel as though I heard that little tidbit of information somewhere and I could connect that to my reality rather well. Does anyone know?

Hi, I don't know much more about your query but I think your are thinking right. I hope other members will give you some useful information soon.

The more tired you are/the longer you've been awake, the deeper the sleep you fall in to. Therefore - if you've slept for 9 hours and then sleep for another cycle, it's likely to be full of REM. If you've been awake for about 6 hours and have an afternoon nap, you should get a good bout of REM. The closer you get to the evening, i.e. the longer you've been awake for, the deeper the sleep and the less REM you'll get. By the time you've been up 14-18 hours and head to bed, you're going to be tired, and should end up straight in deep sleep.
