DEILDS are really easy to do I think.
Before you go to bed plan out when you want to wake up but don't set an alarm and make sure it's during your rem cycle. so what I do is add an hour and an half to the time I go to bed and take account those times, for example if I went to bed at 10:00 I add an hour and half to that till I wake up, so 11:30, 1:00, 2:30, and 4. So pick one of those times(of course yours may be different), pick one that is later, like your 3rd rem cycle and make sure you really think about waking up around this time and you will
I did this and I wake up during every one of my rem cycles, if you want to wake up during each one, just take account of all your rem cycles and tell yourself, "I will wake up during each my rem cycles."
Just a suggestion
