What are the stages of REM sleep?

ANSWER

There are 3 stages:

Stage 1: Your eyes are closed, but it's easy to wake you up. This phase may last for 5 to 10 minutes.

Stage 2: You're in light sleep. Your heart rate slows and your body temperature drops. Your body is getting ready for deep sleep.

Stage 3: This is the deep sleep stage. It's harder to rouse you during this stag. If someone woke you up, you'd feel disoriented for a few minutes.
