Weird dream concerning a corpse in my house and trying to get rid of it.?

I had a dream that I had either murdered someone, or someone had died inside my house while parents were still away on their trip and I was home alone. This corpse had become a problem and i was trying to get rid of it. I cut it into pieces and threw it down the sink drain to have it get cut down and flushed down that sink. I cut the limbs off, feet and hands first, but didn't finish with the rest of the body. As they did, they became maggots as they were cut into pieces, just rising up from the sink with water, then finally drained. I also remember seeing my black cat get inside the sink as I was doing this. Disgusting dream. What could it mean? lol >.<
