I can see why the score is so low. I mean, it's just too brief. The animation it does have isn't that good. It was just some purple guy. I suggest you have more going on. The audio didn't seem that good either.
You need to have more than just a guy in bed. Maybe you could show the bad dream? Some people here have done that, I before. In dreams, you can come up with any insane thing you want. I'm sure you're more creative than you let on.
