Recurring dream of Car crashing into front fence

[The Dreamer]

I kept having a recurring dream for a few years when I was a child which occurred until I moved house. It was of a car crashing into the front sandstone fence. It was always a silver/Grey car and always crashed in the same place and stopped in the same position each time. My first house was in the middle of the street so I am unsure how anyone could crash there.

Each time I was doing something different in the front yard, playing ball, washing the car, collecting the milk. I would be facing toward the house and would turn around to see the car knock the sandstone wall down. No one ever got out and the dream would end there.

But I also had another recurring dream when I was a child where I would go outside the house to collect the mail from the letterbox at night. When I start to walk back a siren would start sounding. I would look back and a police car would be following me up the driveway with its lights on. I would run back inside and the police car would be gone.

But it worried me so much that I would always run from the door to the fence when I was alone (about 80 or so meters each way).Thedreams stopped when my family moved house. I was only young,between 3 and 6 when these dreams occurred
