Screaming or howling

I was at a friends house in Bristol (even though I have never been there to visit this friend yet). I was playing with a dog in the garden when this Jaguar appears so I run into the next garden and gather up my friend, the dog, some other people including children and the neighbours and get them into the house and lock the Jaguar out. One guy in the house has a wound on his face which I ask if he got from the Jaguar but he says no. Suddenly I am back at the house where I live, and am looking out the window at this crazy bitch with dark hair in the street smashing at peoples doors with a shovel. She then comes to ours with an accomplice, a blonde woman with greenish eyes. I call the police and describe what I have seen happen and that they are now at our door harassing us but the police just hang up not caring! So I open the door to confront them but the dark haired woman tries to cut the top of my hand with a rusty garden tool she is took from our porch (like a sickle), but it is too blunt and just sort of scratches my skin. The blonde woman just stands there smirking and I remember seeing a neighbour who I think was another old friend of mine's Mother just watching us out the window (even though she does not even live in this street). I then woke myself up screaming 'GET AWAY!!'. I know why I had this dream because the same night a strange woman rang the doorbell at about 11pm asking for someone called <PERSON> and when I said no-one called <PERSON> lived here she asked if anyone next door was called <PERSON> to which I replied there was no-one round here called <PERSON>. It freaked myself and my Mother out a bit as it was late for someone to be calling and the woman was just weird and shifty most likely mentally ill or on drugs.
