Thread: When will my REM periods occur during the night?

We go through sleep cycles. Each is about 90 min long and starts with NREM and ends with REM. First, as you go to sleep, NREM is about 80 min and REM about 10 min. But as you sleep, NREM gets shorter and REM longer, and by the morning, after 7-8 hrs of sleep, your REM is about 80 min long. Hope this helps.

Oh, thanks!
One more question - chain dreaming can only be done properly during REM sleep right? But what happens when the REM sleep part of a sleep cycle is over and the body is meant to be moving on to NREM...doesn't this render the traditional chain dreaming technique useless? The reason why I ask this is because in the DEILD part of the forums I see people saying how they have chain dreamed up to 5 half hour long dreams and such..

In later part of the sleep NREM can be as long as 80 min, then short NREM and then REM again. If you are skilled, you can stay aware during NREM and chain your DEILDs.

But to chain 5 of half an hour long lucids is quite a feat and you would have to be very skilled.

And we do dream during NREM also, but those dreams are not as vivid or long as those in REM.
