a dream that can cause strong emotions to go off on your brain, usually fear or horror, but also despair, anxiety and even depression.
Nightmares are actually believe to be helpful. They help us prepare for future real situational things in the awaking world. It could even help us survive. The human brain forces us to get ready for similar events.
The five stages are:
Experience drifting in and out of sleep.
Easily woken up (Light sleep).
Experience sudden jerks. (Known as Hypnic Myoclonia and Myoclonic Jerks).
Sensation of falling.
Moves to Stage 2 after 5-15 minutes.
4-5% of whole sleep.
Lasts about 5-10 minutes.
Becoming disengaged from surroundings.
Body temperature drops.
Brain does less complicated tasks.
Sudden bursts of brain activity (Sleep Spindles).
Another 15 minutes to move to Stage 3.
Also know as, 'The Delta Stage'.
45-55% of whole sleep.
Last approximately 20 min.
Transition from light sleep to deep sleep.

What occurs in NREM is..
You may have a dream. (Not as usual as in REM Stage).
The type of dreams you have in NREM is taking the past of the awaking world and trying to figure out how that would probably relate to the future.
75% of the time you sleep is NREM (Stage 1-4).
Very deep sleep. (Deepest Stage)
More than 50% are slow delta waves.
After sleep deprivation. It most likely will cause a sharp rebound.
12-15% of entire sleep.
Brain waves are extremely slow.
Blood flow is directed away from the brain and towards muscles, regaining physical energy.
Stage 5 (REM)
About 70-90 minutes since first feel asleep, you enter REM sleep, where dreaming occurs.
Breathing becomes shallow.
Heart rate and blood pressure increase.
Arms and legs muscles become paralyzed.
Where most dreaming occur. Our eyes actually move back and forth during REM, which is where this stage got its name. (Rapid Eye Movement)
Consists of four stages of sleep, each deeper than the previews stage.
Another requirement in order to have a quality sleep is having both NREM & REM sleeps in uninterrupted cycles.

Rapid Eye Movement.
What occurs during REM is..
Most dreams occur during the REM stage.
Eyes move uncontrollably under our eyelids.
The brain becomes active, while the muscles relax.
You can't move voluntarily because signals from the brain to the muscles are blocked.
The types of dreams you have during REM is trying to experience the future and 'move' into it. (Face challenges)
50% of REM sleep for Newborns & 20% of Adolescents to Elderly. (Elders sleep the least)
