Rapid eye movement (REM) sleep, or stage R, usually starts about 90 minutes after you fall asleep. Brain activity increases, your eyes dart around quickly, and your pulse, blood pressure, and breathing speed up. This is also when you do most of your dreaming. REM sleep is important for learning and memory.
What best describes REM sleep?

The first time your body enters this phase at night, it will stay in REM sleep for 90 to 110 minutes.
