I had this wild, vivid dream..

Three guys go to a ski lodge, and there aren’t enough rooms, so they have to share a bed. In the middle of the night, the guy on the right wakes up and says,
“I had this wild, vivid dream of getting a hand job!”
The guy on the left wakes up, and unbelievably, he’s had the same dream, too.Then the guy in the middle wakes up and says,
“That’s funny, I dreamed I was skiing!”
