bad dream

i had a terrible nightmare this morning. I had a dream that i was at a house on the beach and then there was a big wave and i held on to the doorknob and then after the wave went back then. then i open the door and then i went inside and then i tried to shut the door and there were 3 kids saying trick or treat in a scarey voice and i yelled for brother domanic(i don't have a clue) and he went over and held the door there and then the door opened up and i saw the 3 kids in nosses being hung and the rope was going high and the they were being lifted over the doorway...it was scarey.
