Swimming pools, telephones, and serial killers

I'm afraid to go to sleep tonight. My dreams last night were disturbing; I wasn't always afraid, but I woke intermittently with a start after segments passed. There is a house in my recurring dream that belongs to my mother, but it isn't my mother's house, and there are steps going down in the back out of the kitchen that is too white. The house seems to be an old one and is in a town with sidewalks and where buildings are too close together for my taste. My mother is never there, in the house in the dream. In the same dream there is a swimming pool with a number of women who are trying on swimming suits and diving into the pool.  They don't see to want to wear the suits and some of them remove them in the water. A small girl comes to the side of the pool and yells at me that I am in the wrong place; yes, certainly I know this but the water is nice and I love swimming. The third part of the dream I become separated from myself and watch myself as if on TV. I am doing everything to save the little girl in the next room, even if it means sacrificing myself to the killer. The telephone rings and it is my brother telling me that this has gone on long enough and we should do something, I say something to him but he's put me on hold. He comes back on the line with my other brother who says, "Hi Anne." I say, are all three of you there? The first brother says yes. They say that they know the truth and I tell them that they are wrong; they don't know anything about what is true. They want to know what I mean by that, was I calling them liars? One slams down the phone and I scream at the other something so loud that I cannot understand or hear it myself.
