The Skinwalker's Practice

There's something nobody tells you about skinwalkers. They don't just mimic animals.

My Navajo grandfather said they practice on humans first. A woman would stand outside windows,

perfectly still, just watching. She'd repeat your last words in your voice.

Then she'd smile. She'd knock from inside, asking: 'Can I come

in to get warm?' The knocking still comes. It isn't trying

to get out. It's checking if you're still inside. Don't open the door.
