I had a true and terrifying nightmare last night! Finally my lucid dreaming paid off, as I have been really trying hard to have one. This wasn't a stress dream but  a full on never ending nightmare... A friend and I (at one point it was John Sachs) realized that we could fly, and not just like weird dreaming fly, but absolutely zip around like superman. We then realized we just had unlimited power and he went all Lawnmower Man on me and began just destroying people and breaking my body. There was a lot of pain and fear but I didn't die, was just torn apart over and over. At one point I remember eating his thumb, crunching the knuckle like a hard candy, another he generated a demon shark the size of a building which rose from the depths with eyes of fire and a mouth with never ending teeth. I just could not escape. At one point I flew up to the very edge of the atmosphere where it was freezing and the oxygen was too thin to breath... but I could not escape. I was destroyed over and over and it felt like a Delirium Tremens episode, some vision of a never ending hell where I was just overcome by terrifying madness which I could not stop. I eventually managed to crack my eyes open and I saw my room realized this was the way to escape and I woke myself up... WOW! I had asked for the dark side of lucid dreaming, been warned by people but WOW! It was everything I had hoped for and more... But I really have no fear, having experienced this madness while awake so I just brushed it off, went back to bed and then dreamed I was happily married on a hippy farm and worked in a smoke house...
