Sleep Paralysis
While we’re dreaming, our brain releases a chemical that prevents us from sleepwalking. It paralyzes you. But sometimes, there’s a malfunction in the transition between REM sleep and waking up, so you’re body is still paralyzed but you’re wide awake. It’s usually accompanied by feelings of fear and terror, and some people even get mild visual and auditory hallucinations (The Minds Journal). According to the Sleep Foundation, sleep paralysis involves a mixed state of consciousness. It’s a brief loss of muscle control, and 75% of sleep paralysis episodes involve hallucinations, like intruder hallucinations, vestibular-motor (VM) hallucinations, and chest pressure hallucinations. With intruder hallucinations, you’ll get the feeling someone dangerous is in the room. VM hallucinations include feelings of out-of-body sensations, and chest pressure hallucinations feel like someone is sitting on your chest. These all involve immense feelings of fear, and episodes last from a few seconds to 20 minutes.
