Humans spend an average of 6 years of their lives on dreaming.
But, How many of your dreams can remember?
Many people have a hard time recalling their dream or don’t remember anything at all.
When you sleep your brain goes through four different mental states.
The final stage is Rapid Eye Movement, or REM – is when the brain begins to dream. Eyes move rapidly, hearts rate lowers, the body goes into paralysis, and the level of two chemical in our brain vital to our dream change.
The production of acetylcholine increases, triggering intense activity in the brain. Acetylcholine controls how vivid our dreams appear to us. Meanwhile, norepinephrine, a chemical which regulates our alertness and stress, decreases. Lower levels of norepinephrine help the brain process dreams stress-free, but also reduce the ability to memorize dreams during sleep.
The levels of these two chemicals spike drastically when we fall asleep quickly or wake up to an alarm, making it harder for the brain to retain dreams. Moreover, sometimes the brain doesn’t remember dreams because they are simply not exciting enough.
