it’s frequent I wake up 2-3 times during the night
Did you ever notice the time between wakings? For me it’s three hours pretty much on the dot — i.e. I have a regular 1½-hour cycle, but prefer sleeping for two cycles minimum for some reason, and do the same with naps.
As for the cycle being restarted, REM is deep sleep, so you’re unlikely to get it if you’re woken up all the time.
It’s quite random, the time between wakings. If I go by smartwatch data it’s anywhere between 10 minutes and 4 hours. Consciously remembered ones, those are almost always 2 hours on the dot.
