Why do I have these weird dreams?

Well, I have weird dreams too. That dream sounds SOOOOOOOOOOOO cool. My weird dream is that I'm arguing with a faceless man and I'm in a bus and he's driving a Lotus Elise. Then we're at the race track and we have a drag race and I race his Lotus Elise in a Ford Capri and I win, but the brakes fail and the Capri goes off a cliff and lands in a vat of coke at a Coca-Cola brewery. LOL!
