More to dreams then just sex?

"Well if this is dream could I fly?" you say and suddenly butterfly wings sprout and you fly above the guys. The guys give you a dirty look, and their penises turn into snakes(penis snake) and slither upwards to eat you. You fight back though with your laser rifles in both hands shooting the penissssssssnake to smithereens. But more snakes come to fight you! The nightmare continues and continues until suddenly the snakes have captured you. They then start fucking you like crazy!
"Oumphf!!" the sensation was so strong that it couldn't have been a dream, and if it was your imagination had turned it for the worse.
