I had a dream several months ago where I visited my mom at her old job. She worked in a National Park and had to live in an RV onsite.
In this dream, I was sitting inside the RV with her when a man knocked on the door. She opens it to meet this salesman type guy but... his face is very cherub-like, and unnervingly pale. I would say a fish belly white.
I felt like something was wrong. My mom, sensing the same thing, told me to run.
I jumped out of the RV past him, and he just slightly turned and followed my movement but otherwise did not react. He maintained that smile and turned back to my mom.
She grabs the man by his neck and begins strangling him. The face does not change. As she chokes it, something bizarre happens - his neck.... belongs to elongate.
The more she strangles him, the longer and noodle-like his neck becomes. She wrestles the thing into the RV, and manages to grab onto a hatchet nearby.
