What is a dream?

A dream is something that occurs multiple times a night and is a series of images, thoughts and sensations. You can dream about something positive - something we just call a dream - and you can have nightmares or night terrors. These are just dreams that are scary or negative to us.

What is the brain doing during sleep?

During dreams the whole brain is active, but the cortex that is responsible for the content that you are dreaming about. Throughout the time we sleep, the brain generates two types of sleep-slow-sleep waves (SWS). Slow-wave sleep is also known as deep sleep. The second type of sleep is rapid eye movement (REM).


During REM sleep there is a specific type of electrical activity that happens. When researchers woke people during this stage most of them remember just dreaming. If you look at the electrical activity during REM sleep, it is almost identical to the way the brain acts when you are awake. The difference is the production of certain chemicals (nor-epinephrine, serotonin, and histamine) are not being produced during this time. These cause the muscles to stop moving. Some people that have a disorder can achieve full REM atopia which leads to moving around when you sleep or even sleep walking.
