I did the basic one...

During a pretty vivid LD I decided to do the tasks, since I haven't tried them for quite a long time. I planned to do open heart surgery on myself while falling off a building, as mentioned by AnonymousTipster. I jumped onto the roof of a ~100 storey building, then felt around for a tool to use for my surgery, ending up with a pencil. I kind of chickened out at the thought of stabbing a pencil into my own chest, so I decided to scrap the surgery part and just dive off. Before hitting the ground I flew away. I flew feet-first towards the creepy looking Burger King mascot who was sitting on a bench ahead, and kicked the crown off his head. I woke up shortly after.
