Help me understand my dream?

In the last week, I had this dream for 2 nights straight. The thing is it’s pitch dark around me. Its night time and I am standing on the street. I walk around a bit. Then, I see a house. The house sort of stirs some familiar feeling inside me. I want to enter the house. Maybe a friend lived there. Can’t really recall. Anyway after a moment or two, I choose not to go to the house. Don’t know why again. At that precise point, a black vicious looking dog runs towards me. I try to run, but he catches me nonetheless. As soon as he starts biting me, I wake up.

I am kind of scared of dogs, but I don’t think its the major focus in this dream. And the dog is the image I have of the most vicious one, you know the black evil looking sort of thing. Something about running away from something, a fear or something ? Help pls
