I had a dream last night that a girl was in the fetal position under a blanket, and took a butcher knife and killed herself under the blanket. The dream then went on with me walking around a house that I guess was mine, and I was outside walking by the pool and found a dead animal carcass of a labrador. I went inside and got a call from a serial killer that had been calling people to tell them that he was attacking when they least expected it, which he told me the same thing, and he started planting dead animal carcasses around the outside of the house at every doorway. I remember being scared and scatter brained.
The girl and the animals that are killed could represent aspects of your personality that are changing. The kinds of animals could provide clues about what aspects of your personality are changing. Have you by any chance read any books or seen any films about a serial killer recently?
