David Lynch is such a genius.
You see I was watching Mulholland Dr., and I was kinda sleepy, so then I fall asleep for like 15 seconds, and the increasing sounds wakes me up, and I look to the screen and I see the God damn "Man" the character was talking about that he saw in his dreams, who looks like... demonic would be a semi-good description. Of course, I turn the lights off to watch a good movie, specially movies like Lynch's which have such great ambience.
So yeah, I'm asleep, lights off, wake up, first thing I see is the freaking scary "Man" as the music gets increasingly intense... My reaction is obvious.
