Dreams are basically images, sounds, thoughts, and sensations created while one sleeps. They can happen at any time when asleep. They include people you know, strangers you’ve seen pass by, places you’ve been, and places you’ve seen. Whatever that is seen in a dream is something you have seen somewhere in your lifeline, as the brain cannot create without being concious.

​

Experts say that a person on average dreams 4 to 6 times and they last from a few minutes up to 30. The time becomes longer as the sleep cycle progresses.

The most vivid dreams happen when during the REM phase (Rapid Eye Movement), it’s the time where your brain is most active. During this stage, your heart rate and breathing become inconsistent, blood pressure rises, and paralysis in your skeletal muscles occur; We can’t regulate our body temperature and brain activity raises up to level alpha which is equivalent to the level of our brain activity when we’re awake, sometimes it goes even higher.

​

During the REM sleep, the body is forcibly paralyzed in order

to enable it from acting out physically. It’s caused because of

the release of glycine and amino acid from the brain stem

onto the motoneurons.

 

REM sleep was discovered in 953 by the University of

Chicago, the researchers: Eugine Aserinsky, a

graduate in physiology and Nathaniel Kleitman→

Ph.D., chair of physiology
