2. Sleep Paralysis is Not a Nightmare (at least Scientifically)
Many people associate the feeling of not being able to move as part of a nightmare, but unpleasant images from true nightmares actually only occur when you’re in a deep state of sleep. Sleep paralysis is essentially the opposite of a nightmare, due to when it occurs in the sleep cycle.
WebMD notes that sleep paralysis only takes place when you’re transitioning into a sleep mode (hypnagogic), or coming out of it (hypnopompic). Sleep paralysis is arguably more terrifying than a nightmare, due to the fact you’re conscious yet seem helpless against any perceived dangers.
