Common Questions About Sleep

How long is a full sleep cycle?
Together, the stages of REM and non-REM sleep form a complete sleep cycle. Each cycle typically lasts about 90 minutes and repeats four to six times over the course of a night. The amount of time you spend in each stage of sleep changes as the night progresses.

What is REM sleep?
Rapid eye movement sleep (REM sleep, REMS) is a unique phase of mammalian sleep characterized by random movement of the eyes, low muscle tone throughout the body, and the propensity of the sleeper to dream vividly.

Do you dream in deep sleep?
Non-REM (NREM) sleep consists of three stages of sleep, each deeper than the last. REM (Rapid Eye Movement) sleep is when you do most active dreaming. Your eyes actually move back and forth during this stage, which is why it is called Rapid Eye Movement sleep.

Do you dream only in REM sleep?
Illogical experiences we call dreams almost always occur during REM sleep. While most mammals and birds show signs of REM sleep, reptiles and other cold-blooded animals do not. REM sleep begins with signals from an area at the base of the brain called the pons.

Invisible Qualities

http://bible.com/111/rom.1.19-20.niv since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
