Often the most reported paranormal event that is in no way paranormal. Some people report that while trying to get out of bed they suddenly feel as though someone is holding them down and they become unable to move their body. Over the years this phenomenon has been come to be known as “Old Hag Syndrome”, the name of the phenomenon comes from the superstitious belief that a witch - or an old hag - sits or "rides" the chest of the victims, rendering them immobile. Although that explanation isn't taken very seriously nowadays, the perplexing and often very frightening nature of the phenomenon leads many people to believe that there are supernatural forces at work - ghosts or demons.
        Sleep paralysis is a condition where as a person attempts to get up and out of bed and suddenly realizes they are completely paralyzed. The experience is so frightening because the victims, although paralyzed, seem to have full use of their senses. In fact, it is often accompanied by strange smells, the sound of approaching footsteps, apparitions of weird shadows or glowing eyes, and the oppressive weight on the chest, making breathing difficult if not impossible. All of the body's senses are telling the victims that something real and unusual is happening to them. The spell is broken and the victims recover often on the point of losing consciousness. Fully awake and well, they sit up, completely baffled by what just happened to them since now the room is entirely normal.
        The phenomenon occurs to both men and women of various ages and seems to happen to about 15 percent of the population at least once in a lifetime. It can occur while the victim is sleeping during the day or night, and it is a worldwide phenomenon that has been documented since ancient times. "In the 2nd century, the Greek physician Galen attributed it to indigestion," according to The Encyclopedia of Ghosts and Spirits by Rosemary Ellen Guiley. "Some individuals suffer repeated attacks over a limited period of time; others have repeated attacks for years."
        So what causes it? Dr. Max Hirshkowitz, director of the Sleep Disorders Center at the Veterans Administration Medical Center in Houston, says that sleep paralysis occurs when the brain is in the transition state between deep, dreaming sleep (known as REM sleep for its rapid eye movement) and waking up. During REM dreaming sleep, the brain has turned off most of the body's muscle function so we cannot act out our dreams - we are temporarily paralyzed. "Sometimes your brain doesn't fully switch off those dreams - or the paralysis - when you wake up, that would explain the 'frozen' feeling and hallucinations associated with sleep paralysis." According to his research, the effect only really lasts from a few seconds to as long as a minute, but in this half-dream half-awake state, to the victim it can seem much longer. For all their explanations, however, the sleep experts still do not know what causes the brain to screw up like this, or why some people experience it more than others.
