I had a lucid dream last night, one that lasted all of 10 seconds because I tried to jump through a floor before figuring out what would be under it. This happens to me too often, since I have too much ambition and too little planning ahead of time, I often rush into something without thinking about it before hand. So can you give my stupidly ambitious self ideas on what to do in my lucid dreams?

Things I've done;

fly;
create dream characters;
urinate;
change the shape of my body;
attempts at sex, usually leading to waking up;
float in midair.
