Dream with disturbing imagery last night:

I'm with my sister and we drive up to a house where there is a bird coup and next to it is a huge mailbox that resembles a trash bin. I put something in it (don't recall what it was) and then we head down the road. In the road are several dogs. The dogs are the pure-bred breed Irish Setters. Some of the dogs have been run over. Their body parts are still in the road, sqashed with blood and entrails. The surviving Setters are lying down next to the broken bodies, seeming sad as in mourning.

I'm stumped as to what this could be about!
