Before the 1950's, scientists used to believe that as people drifted off to sleep, their brains and bodies would go into “shutdown” mode, entering a passive state that allowed them to recover from the previous day.

If sleep disorders like insomnia and sleep apnea have been ruled out, it is very possible that a lack of REM sleep is to blame. REM sleep is a very important stage in a healthy sleep cycle. More and more evidence is suggesting that a lack of REM sleep can be to blame for many people's problems with not feeling rested in the morning.

Normal sleep starts with 3 stages of NREM sleep at first, followed by a short period of REM sleep. NREM and REM sleep then alternates throughout the night. During the latter part of the night, REM sleep is more prominent. If you have narcolepsy, this pattern is much more fragmented and you may wake several times during the night.
Deep sleep occurs in the final stage of non-REM sleep. During this stage, your breathing is the slowest it is during sleep, and you're unlikely to be awoken by loud noises. You may experience less.
