If you have had a dream like this before, you may have experienced sleep paralysis. According to Kenneth Moss, M.D., a sleep specialist with Henry Ford Health, sleep paralysis it is the sensation of being paralyzed that occurs while you sleep. And don't worry – it can happen to anyone.
Why does sleep paralysis happen? During the rapid eye movement (REM) sleep stage, you're likely to have dreams. The brain prevents muscles in your limbs from moving to protect yourself from acting dreams out and hurting yourself. Sleep paralysis happens when you regain awareness going into or coming out of REM.
Causes of sleep paralysis

During sleep paralysis, the crisp dreams of REM “spill over” into waking consciousness like a dream coming alive before your eyes—fanged figures and all. These hallucinations—often involving seeing and sensing ghostly bedroom intruders—are interpreted differently around the world.

Sleep paralysis is not life threatening, but it can cause anxiety. It can happen alongside other sleep disorders, such as narcolepsy. It often starts during adolescence, and it can become frequent during the 20s and 30s. It affects approximately 7.6% of people in their life.

Nerve pathways in the brain that prevent muscles from moving are active during normal REM or dreaming sleep, resulting in temporary paralysis of your body. In REM sleep behavior disorder, these pathways no longer work and you may physically act out your dreams.
It is may also be helpful to offer a method of 'breaking' the episode of sleep paralysis once it has started. Anecdotally, many sufferers find that moving a small muscle, such as the eyes, fingers or toes, can allow them to snap out of the paralysis.
Who is at risk for sleep paralysis? This phenomenon may happen more often than you'd think, as seven to eight percent of the population may experience sleep paralysis. It is more frequent in African-Americans, young adults and females.
Sleep demons are frightening phenomena that are all too real for people who experience sleep paralysis. Roughly 20% of people have an episode of sleep paralysis at least occasionally. In as many as 75% of these episodes, the sleeper has a hallucination.

Although some theorists have suggested that pain sensations cannot be part of the dreaming world, research has shown that pain sensations occur in about 1% of the dreams in healthy persons and in about 30% of patients with acute, severe pain.
The sensory impact of sleep paralysis could even be sounds or smells, or physical sensations such as feeling like something is pressing you down, or that you are being watched or touched. All of this adds to the way this sleep-related PTSD symptom can be severely distressing.
Is Sleep Paralysis a Symptom of a Serious Problem? Sleep researchers conclude that, in most cases, sleep paralysis is simply a sign that your body is not moving smoothly through the stages of sleep. Rarely is sleep paralysis linked to deep underlying psychiatric problems.
Recurrent isolated sleep paralysis (RISP) is a type of REM parasomnia. Individuals experiencing anxiety disorders, PTSD, exposure to chronic stress, or shift work are at risk of developing this sleep disorder.
