Unique fingerprints: No two people have the same set of fingerprints, even identical twins. This fact has made fingerprints a crucial tool in forensic science.
Rapid eye movement (REM) dreams: Most vivid and memorable dreams occur during REM sleep, a stage that typically happens several times during the night, with each period lasting longer as the night progresses.
Involuntary muscle twitching: The sensation of "falling" that sometimes jerks you awake when drifting off to sleep is known as a hypnagogic jerk. It's an involuntary muscle spasm that can be quite startling.
