In my most recent 'nightmare' two people were testing out teleportation. They were sending everything from pencils to books to themselves. One person who was watching eventually got fed up, believing it to be a trick, and walked into the zone where the items were appearing, wondering what the trick was. Just as he was about to leave, the people testing the teleporter threw in a cup of pencils. The 'nightmare' faded with the man falling to the ground, and someone asking him if he was alright.
Death by having your organs punctured and moved out of place by something suddenly placed in your body. A horrible way to go, to be sure, yet I didn't believe it was a bad dream. I felt no fear, nor remorse for what happened. In fact, all I did was roll over, pull the sheets up, and say "Hmph... what an idiot." Before falling back asleep.
