Hall of Infinite Doors

[There seems to be a lot of laughing doors...anyway] You stand at a door that looks like a clown face (red nose and everything). The knob was the clowns flower and it squeaked as you turned it. You pushed the door open and creaked all the way like it had been never opened (Not surprised by how far down the hall it is). You walk in every step you take echoes as you continue in to the darkness.

There was a low maniacal laughter that started to rise in the darkness. You look around to see where its coming from but don't see anything darkness.
