Dream of person, roof, hands, killer

I cannot remember the first part of my dream, but I remember there being multiple killings, they all hit one of my family members. Then, I am in a house that I used to live in. Then suddenly, I see my dog shot through the back of her head. The blood spews everywhere. I scream and turn around and tell everybody. Then once I turn around again, she is sitting in my brother's lap and she is unhurt. Everybody calls me crazy. Then, my dream cuts to another part that I don't remember, but someone is murdered. Eventually, my dream cuts to a part where somebody is shot through the window. I see this person get shot, but nobody else sees it. I am called crazy once again. But they believe me at some random point in the dream, and we go after the killer. We end up in a mall and I see a set of windows with tonnes of bullet holes in them. I look through a window and see a man with a gun looking down at us. I scream "run" and drag them down the hall a bit. I end up in a bathroom, but my backpack fills with water. It makes a lot of noise, and I give up and walk out of the bathroom. I see the killer and he walks up to me and asks me where my family is since he wants to skin them. I trick him, saying that I would take him to them since I wanted to skin them alive too(when I didn't). I take him to the roof, where he tells me something along the lines of "I'm trying this new thing where I take people on blind dates before I kill them". Then as I'm swinging him off of the roof (when he appeared in front of me, I took both of his hands in mine so he wouldn't reach for a weapon), I wake up, quite abruptly.
