In the early 2010s I remember reading about a eye mask that detected when you were in REM sleep by the literal rapid movements of your eyeballs while you slept. When REM was sufficiently detected it would flash three red LEDs over your eyes. The idea being that in your dream you would see the three red LEDs faintly, and realise that you were in a dream.
I'm not sure if this actually works or how accurate it was however.

In this case they claim to detect hypnagogia which from the article is the early transition from wakefulness to sleep. In this stage you might have muscle relaxation or breathing pattern changes but probably not rapid eye movement.
