Dreamer's Demise - A clash of cultists

A one episode podcast turned short-story: A lesser practitioner of the occult arts, eagerly delving in the dreamlands to reap secret benefits for his selfish existence, learns a lesson of horror, when unknown forces rip his dreaming self out of the dreamlands, and also make his physical body wake-up, as inmate of a spooky mental hospital. Neo-Lovecraftian theme, inspired by the newer tabletop roleplaying games I delved in.
