THE UNTOLD MYSTRY OF NIGHT MARES

Nightmares are just simple scary images created by brain and sent to the eyes to mark one wake up.
This occurs when one sleeps in apposition that interferes with blood flow .for example, when one sleeps with arms and legs folded, or just over folding of the body during sleep, blood vessels are pressed and a high pressure is created in the heart .this triggers the chemo-receptors of endometrial walls of the cardiac muscles to send impulses to the brain in response creates the scary images sending them to the retinal receptors that enable a person in sleep to view them. This takes some time.
A person in abed sleeping posture wakes up and get scared no more. Stretch and lie well on your bed and enjoy bed when going to sleep.
It that simple.
