With DEILD, no techniques,
of any kind, are necessary,
period; all they serve to do is wake you up more, and remove you from the exit dream. No
noise,
like vibrations, etc, should happen at all, because you are
already dreaming, and the
WILD transition noise simply should not occur. There is no need to worry about your REM periods (or the stuff you've implanted in your mind about REM cycles) because you are still in REM because
you are still dreaming. And, of course, alarms are not necessary, because in a DEILD transition you don't even have to wake up at all, much less be woken up fully. All you need to do is hang onto the dream and let your body go quickly back to sleep.
