I'm not a lucid dreamer, but if I ever become proficient at it, I'll definitely pwn some enemies. I only have one way that I'm really looking forward to, and I've put thought into it before. Here's the story.
Some time in the recent past, before I learned about lucid dreams, I thought that a cool superpower/ability to have would be dream control. I'm talking invading people's dreams and messin' with 'em! Also, going to friends' dreams, then we'd hang out. Aw man, it'd be great! See, what you do is invade the dreams of people you despise (not unlike Bill O'Reilly), dress in all black with a hood, and totally pwn them, causing them to wake up with a start. 'What a strange dream!' they'd say. Then, over time, you tell them to do things, and if they don't, you continue to haunt their dreams. A strange story, fantasy, yes, I know.
Anyways! Back to the part where I tell you my favorite way of imagining to pwn someone. You get a flail. A flail is a spiky ball on a chain on a stick. Also called a morning star, but many people call it a mace, but that's incorrect.
So! What you do is take the mace and swing it really fast and hit the side of their face, and it goes through their head and splatters brains and other head-matter everywhere! BLAM! SPLAT! Gruesome, yet satisfying.
Well, there's my way of killing DC's that I definitely will try someday.
Hopefully you all don't think I'm crazy ahahahah! :D :P
