Sleep can mean several different things in World of Warcraft:
- A prone non-combat position where a character lies down on whatever they are sitting or standing on.
- Characters can be made to sleep or lie down by typing /sleep
- Characters currently 'sleeping' will always suffer a critical strike when hit by any non-spell attack.
- The Sleep effect, which causes players to be unable to move or act until the effect expires or is removed by taking damage.
- A variety of spells and abilities that cause a sleep-like state (see Sleep effect).
- A term for logging off while in a capital city, inn or other areas where your character will accumulate the Rested bonus at approximately 4 times the normal speed (indicated by a 'zzz' on your character portrait).
- The mage spell , which was changed to in patch 0.8.
