Screaming or howling

I was in the kitchen, and I got a phone call from an old friend named <PERSON>. She told me that she was having a party tonight and that I was welcome to come. I said that I would, but remembered that finals were tomorrow (in the dream, not rl) so I told her that I would not stay too late. I arrived at the party and there were tons of cars parked on the grass and around the house. That is the last thing I remember for awhile. I wake up again, screaming. There are two 'men' on me, but one is actually a giant red octopus. I am being violently raped by these two men, and still screaming at the top of my lungs. There is blood all over the sheets and I cannot see my attackers well because it is dark in the room. I tried to escape but passed out again. I woke up alone in the same room, which I recognized to be my old bedroom. Blood had stained the sheets and next to me in the bed are hundreds of dead ladybugs. Across the room is the electric piano, which has split itself down the middle (when I was a child I used to have recurring nightmares about being attacked by an electric piano). I scooted the chair back into place and put the two halves of the piano together again. I left the house and stumbled down the driveway. There was a girl throwing up chocolate cake near the edge of the driveway. Cars were still parked outside the house even though it was pretty dark and empty now. In my head I heard a whispering "Wake up, wake up, wake up!". I woke up IRL, it was 9am which was the time that I had aimed to wake up at... that dream was so disturbing
