The other night i was in a lucid dream, and in it i was talking to my best friend james, and i was trying to figure out if he was really james, or if he was just a figment of my mind. i was very convinced that it was actually him, and that somehow we as people were connected cause we were both asleep. I asked him what his favorite video-game was, to try to see if he was real. He said "quake 2" and that convinced me that he was real, since i wasn't sure what his favorite video game really was, and we had never played quake 2 together so i couldn't have come up with it myself. So basically i duped myself in the dream, although i now know that quake 2 isn't his favorite game, thus proving him a figment of my imagination haha
