REM Rebound
Definition
REM rebound is the lengthening and increasing frequency and depth of rapid eye movement (REM) sleep which occurs after periods of sleep deprivation.
Analogy
Imagine if you've been on a diet for a week, and then you're presented with your favorite meal. You'd likely eat more of it than usual to make up for what you missed out on. That's similar to REM rebound - your brain tries to catch up on the REM sleep it missed out on during sleep deprivation.
