So I know that we actually wake up after every REM cycle throughout the night, but we usually don't remember it. Well a few nights ago, I did actually fully wake up in the middle of the night, so I figured that was the end of one of my cycles. I attempted a WILD (although not successful).

As someone trying to master WILD, I know that it is important to find the start of my REM cycles, however I don't know how to do this. Is there any way that I can use a mantra or something to "train" myself to fully wake up after every REM cycle?
