In the dream I went to someones beach house, located on one of the barrier islands south of Long Island.
they didn’t answer the door. It was night and the lights were on so I went around back to see if they were in the yard.
The sliding glass door was open so I went in, I saw a knife on the floor so I picked it up and put it on the kitchen counter calling the persons name ( I have no idea who it was now)
I rounded a corner and found them dead, apparently stabbed to death.
I grabbed them and tried to resuscitate them , covering myself in blood
Then I heard police cars coming, panicked and ran out and hid in the bushes
