DEILD or express WILD
FILD can only work if you do it few seconds before a REM sleep begins, but when you fall asleep, you don't directly enter in the REM stage.
First you cross N-REM stages 1,2 at least, and if you have still some N-REM stage 3 to go with, you will probably have to deal with this schedule:
1,2,3,2,REM.
when you are awoken directly from the beginning of REM sleep, you will have less N-REM stages to cross before N-REM sleep starts again.
Natural micro awakenings are generally happening after a REM stage is over.
In this case, you won't have REM sleep before the next cycle.
You can wake up during REM sleep naturally, at least during the Tonic REM sleep, but a Device like REM-Dreamer makes it more simple and more certain.
