I understand during the night after around 5-6 hours of sleep and attempting one in conjunction with a WBTB, but how about after having already been awake for several hours. I tend to wake up on weekends around 9:30 AM or so, depends on the schedule for the day. Naps for me tend to be usually around 2:00 PM. Sometimes it is quite bright in the room and there doesn't seem to be the night-time "sleepiness" I figure you would need to have a dream. This might also pose another question for me, is there really REM sleep during naps? At least most of the time for me, there doesn't seem to be any true sleep but just an idle closing of my eyes and when sleep occurs, it tends to be light sleep. Perhaps I am not napping long enough for a normal DILD.

I try to place some fabric over my eyes to cover them from the light, afterward I just relax like normal but end up getting stuck after the normal steps. I am aware sleep paralysis isn't totally necessary for it to work, but at least for naps it seems to be one way for me to actively engage in trying to succeed in it.
