A Blonde's Dream

One day a blonde kept having the same weird dream everyday, so she went to her doctor. Doctor: What was your dream about? Blonde: I was being chase by a vampire! Doctor: (giggles quitely) So... what is the scenery like? Blonde: I was running in a hall way. Doctor: Then what happened? Blonde: Well that's the weird thing. In every single dream, the same thing happened. I always come to this door, but I can't open it. I keep pushing the door and pushing the door, but it wouldn't budge! Doctor: Does the door have any letters on it? Blonde: Yes it did. Doctor: And what did these letter spell? Blonde: It said "Pull"
