Nightmares

I just woke up from a horrible one where all the fingers on my left hand were chopped off (i'm a guitarist) and i could telepathically hear my girlfriend fucking someone else.
Dreams are weird. Share your nightmares with me.

Not a nightmare, but when I was five I slept directly above the laundry room.  I could always hear the faint whirring of the washing machine as I tried to go to sleep.  To my five year old ears though, it sounded like an army of gnomes chanting "We, are, coming...we, are, coming."  And if that wasn't scary enough, there was also the menacing closet doors and the tree outside the window!
