One of the most scary nightmarish scenes in Dawn of the Dead was for me when the little girl attacked the couple had just woke up. Due to this id love to see a Sleeping and Sleeping Encounters.
Sleeping was already mentioned here in this thread (for bonuses). Id love to see the scary part of sleeping with encounters. I picture it like rolls that are influenced by your location/how hidden you are and also by a skill. The better your skill and the better your hiding place the less likely you will wake up to a Zombie eating you. Maybe the numeric roll also determines not only if there is an encounter but also your chance of waking up when the Zombie breaks in your sleeping room. Again skill can increase your chances there and waking up early enough would give you at least some time to prepare. However there should be no 100% safety from a Zombie encounter happening in your sleep and then you would have to fight for your life, no easy escape.
