Once I had a dream where I killed Voldemort by punching him in the face. What was weird about it was that, in the dream, he was standing next to my bed in my room in the morning. When I punched him, he dissolved into thin air, and I woke up with my fist extended out and looking at exactly what I saw in my dream: my room. From the exact same angle, too. And exact same lighting. It was as though it really happened...it was so weird.
