Wake up in the middle of the night to pee:
Avoid all mirrors.

Airplane engine makes a sudden noise:
I lived a good life.

Hear thumps while in the shower: Your family is being killed and your next.

Turn off all light before going to bed:
OMG run for the bed before the demons get you.

Elevator door doesn't open immediately: Trapped forever.

Realize it's too quiet, where's everyone?: Oh g** zombies.
