When you dream, your body is
paralyzed
In the first 90 minutes of
sleep, you go through deepening stages ranging from light sleep to deep sleep. Then
you enter a phase called REM sleep (REM is short for Rapid Eye
Movement) During REM sleep, the rest of your body essentially becomes
paralyzed. The release of certain neurotransmitters are shut down and your
large muscles do not move.Some people have abnormal
REM sleep in which those neurotransmitters do not shut down, and they act out
their dreams. Most of the dreams we vividly remember happen during REM, as our
brain has higher activity during this phase.
Blind People Dream
People who become blind after birth can see images in their
dreams. People who are born blind do not see any images, but have dreams
equally vivid involving their other senses of sound, smell, touch and emotion.
It is hard for a seeing person to imagine, but the body’s need for sleep is so
strong that it is able to handle virtually all physical situations to make it
happen.
