Nachtmahr - A Nachtmahr is a giant fart monster that lives in your head

A Nachtmahr is a giant fart monster that lives in your head and makes your dreams smell like old socks. You can't sleep because it's always pooping.

I tried to sleep, but my brain was full of fart smells. My Nachtmahr had broken into my house and was throwing a poop party.

I had a dream about being trapped in a sock. My Nachtmahr had taken over my brain.

My Nachtmahr woke me up at 3 a. m. with a loud fart and a scream. I was too tired to yell at it.
