Last night as I lay down to sleep, my thoughts centered on visualizing a lucid-induction hallway for me to walk down as I slowly made my way into dreamland.

I visualized a brightly-lit hallway with a door at the end, a sign hanging above which said "YOU ARE LUCID DREAMING." As I approached this doorway and turned the knob, a tattoo on my right forearm reminded me, "You Are In A Dream." Then as I stepped into the doorway, I imagined a portal with the letters "LD" above it and a happy old Santa Claus look-alike ushering me into the portal, welcoming me to a dream. As I stepped through the portal, I imagined the start of my dream world.

This scene ran through my head over and over until I fell asleep. I dreamt, but what I got instead was the long corridor of a mall, a flat-level escalator leading me into a doorway which opened into the Lair of Hell, with the devil himself there ushering me into the portal to hell.

That is not exactly what I visualized! And as a result, I did not get a lucid dream, rather a very grotesque dream in which I attempted to kill the devil, which was a success, until the devil took over the body of a DC which was a dream-friend of mine -- not to mention my dream parents were 30 years younger than my real-life parents and were devil bounty hunters.

How did my simplistic visualization possibly lead into such a perversion of my original intention?
