I believe that only mexican zombies sleep, during siesta. They probably just lean against a donkey and pull their sombrero over their eyes. Freaking mexican zombies.
Zombies only sleep when they are captured by non-zombies... mainly because the non-zombies will slowly torture the zombie, inflicting as much pain as possible. The non-zombies may cut off the zombies fingers and eat them in front of the zombie... provoking the zombie... if you will. After that the non-zombies will slowly begin cutting the zombie into tiny pieces, at this point the zombie knows it's screwed and begins saying it's prayers to the zombie GOD. If the zombies are lucky, the zombie GOD will answer their pitiful prayers and send more zombies to help them out, but since zombie's have no souls, this rarely happens. So soon enough, all that will be left of the zombie is it's head... because the rest of it's body has been mutilated. The sight of this will cause the zombie to go into shock... and slowly lose conscientiousness, thus the zombie will be "sleeping". But the zombie will never wake up, because it's eyes will be resting in a non-zombies stomach, smashed up and unrecognizable, and unusable. It's quite the process... but I don't make up the rules, k Tphrz? I just enforce them with my limited authority.
