I had my first LDs catching a recurring nightmare where my body would be forced from my bed and towards some sort of electronic device. I would just use my lucidity to wake myself up. One time in one of the dreams, it was towards a digital alarm clock that changed from numbers, to a monster, and to the words, "THE END" as I was pulled towards it.

I kept having these nightmares until a few years ago, when I become confident enough in my dreaming abilities where I thought, "screw it. I'm going to see where this force takes me." In the dream, the force took me out of my house to a series of dark rooms where I had to fight large spiders and such. After I was done fighting, I came into a futuristic room where an old scientist approached me and told me his observations on how I did fighting the DCs. I've never had the same nightmare since.
