Quizplus · Accepted Answer

Lance has experienced sleep paralysis, which is a common phenomenon during REM sleep in which the body is temporarily paralyzed but the brain is still active. Wakening during this phase can lead to a brief episode of feeling unable to move, as described in the question. Night terrors are a different sleep disorder characterized by sudden awakenings with intense fear and panic, and hypnagogic movement refers to involuntary jerkiness that can occur as one is falling asleep. Delta wave paralysis is not a known sleep disorder.
