Sleep, for the purposes of this post, is any "knockout" effect, including but not limited to: sleep, cold be sleep, blackjack, weapon butt blackjack, knockout poison, knockout trap, strangle, choke, cranial, strangle, and stun.

1) These effects are generally shorter in duration across the board by a tick or two (or more), though not all have been touched.

2) Using offensive/harmful spells/powers/communes/etc. on someone who has been slept by someone who isn't you has a small (~5%) chance to wake them.
