A blonde keeps having the same weird dream, so she goes to her psychologist.
Psychologist: What is your dream about?
Blonde: I am being chased by a vampire…
Psychologist: So, where are you in this dream?
Blonde: I am running in a hallway.
Psychologist: Then what happens?
Blonde: Well, that’s the weird thing. In every single dream, the same thing happens. I always come to a door, but I can’t open it. I keep pushing the door and pushing the door, but it won’t budge!
Psychologist: Does the door have any letters on it?
Blonde: Yes.
Psychologist: And what do these letter spell?
Blonde: P-U-L-L.
