Strange dreams

I had a very strange nightmare that melded the transportation system used in Gringotts Wizarding Bank from J.K. Rowling's Harry Potter series, the heartless shadow monsters from the Kingdom Hearts action role-playing game, a tree house from a Pokemon game (probably Ruby), various locations in real life, fish skeletons, a race, and general unhappiness. Considering I haven't thought about Harry Potter, Kingdom Hearts, or Pokemon in a very long time, I awoke from the dream very confused. Also, I think I punched something in my dream with my left hand (I'm actually right-handed in real life, but in my dream I was left-handed), and when I woke up my knuckles on my left hand were red. How funny!
