Because of this experience I don't doubt the part that says you can make the sound go away.

This technique also presents something interesting that I did not know about - the R.E.M. period when first falling asleep. Is this significant enough to have a long, vivid lucid dream? Regardless, I thinks it's definitely worth trying for me since I would rather have a placebo-induced lucid dream than no lucid dream, but as Sageous pointed out, it's best to be safe and not forget about the other aspects of lucid dreaming.
Thanks for the input.
I tend to believe the brain is absolutely able to ignore the external stimulus to prevent the dreamer when waking up.
Especially during phasic REM.
these last few weeks I have been experiencing a lot with my REM-DREAMER to wake me up briefly during REM sleep to train at DEILD, and sometimes there is no way I can hear and see the flash/beeps the mask is producing.

I don't understand what is the interesting thing you didn't know about in your second paragraph and what your question exactly is.
