Craziest dream in a while...?

in the dream i was outside on a sidewalk at night outside a door, i walked in the door to find a room that had nothing in it except a chair that looked like an electric chair and a projection screen in front of it. no one else was around, and i had never been there before, but i knew how to work the thing. if you sat in the chair and asked a question about yourself that you were unsure of (ie: what's your favorite song, and you don't know) the machine could search your brain for the exact answer and project it on the screen. i asked, what am i most afraid of? and on the screen were the dixie chicks standing in the middle of the road at night, i was sitting in a parked car watching them in front of me, when a small flying saucer came out of nowhere, sliced off their heads, and flew off. the fell over, dead, and i got out of the chair and woke up.
