1.
A falling poster in the middle of the night.
2.
The first time the heating turns on.
3.
When the floorboard directly outside your bedroom door shifts.
4.
Toxic sludge pouring out of the faucets.
5.
All your lightbulbs burning out at once.
7.
That ominous rumbling of something that's hungry.
8.
Doors slamming shut for no apparent reason.
9.
And then this happens when you try and get out.
10.
When you're rinsing shampoo out of your hair and shower curtain liner suddenly clings to you.
11.
And finally when your pet stares at literally nothing for a long time.
