Discuss the 5 stages of sleep.

In general, each cycle moves sequentially through each stage of sleep: wake, light sleep, deep sleep, REM, and repeat. Cycles earlier in the night tend to have more deep sleep while later cycles have a higher proportion of REM. By the final cycle, your body may even choose to skip deep sleep altogether.
