Whilst you're in a deep sleep/sub concious state, its as if a ninja has sneaked up on you, shoved you and vanished into thin air causing your arms and/or legs to spasm and jump randomly - sometimes so violent that it causes you to wake up.
Just got back from my night-shift at work, got into bed where my girlfriend was sound asleep, she ninja jumped and kicked me in the fucking gooch!
