After my wife disappeared, strange things started happening in our house.
Every day new words in blood appear on the bathroom mirror: I'm back.
After the alarm failed, I installed surveillance cameras, only to find that I was talking to the air late at night in the camera.
Until today, I found my wife's diary under the bed.
The last page reads:
"My husband suffers from severe sleepwalking. He always pretends to be another person in the middle of the night...
... And I had to cooperate with him or he would kill me. "
But the handwriting is clearly my own.
