Just about everyone has either experienced or heard someone say they were pressed at night. It is usually understood that an evil personality comes into the room or wherever they were sleeping and choked them. In such a state the individual is unable to move or speak audibly, they may speak in faint whispers. After a period of struggle, the victim seems to gain freedom and can move or speak again. The evil presence or personality seemingly disappears from the room and everything gets back to normal, leaving the victim probably sweating, panting, or generally terrified by the experience. This simply explains an episode of sleep paralysis. According to science, it is a harmless medical condition we should all get to understand and learn how to respond to.
