The haunted hair

We were driving to the job, 4 colleagues and me. As I'm a college boy and still I study in university, the work I do to pay off my debts is as a waitress on weekends. A tiny issue for my sleep cycle due to the days I work, I fall asleep at 4:00 am of the next day. The cold on early morning is tough and reaches the bones, and if still raining my fingers get frezze and makes harder to get back to my home. Fortunately, as I already said it, now I have a car to go to work. I really enjoy more using my motorcycle than driving in the car and getting caught in traffic, but it allows me to carry on more people from my job and get an extra money for picking them up and leaving them at their homes. That day, I got out of my car and had a strange sensation of watching the muffler of the car. I found out a bunch of hair in the car exhaust, which was obstructing the gas of my vehicle. I had no time to remove all the hair so I left more than half inside the car. At my home, I removed all the hair. I'm not joking when I say that amount of hair was 5 kilograms at least. And, strangely, the color of the hair was like mine and my mother's. One week later, a friend of ours went to our home, she is a witcher, as she was getting in to the house, she noticed that there was something wrong in the place. We told her what happened that day, "It's a witchcraft," she said at the time we were ending our story. "That hair was recollected and inserted in your car so you both had an accident and lost, at least, the car". She still do'nt see the person who did this, she only sees in her "visions" a tiny, skinny, old and short-cut hair doing this witchcraft, her hatred of us is so big that this is not the first time she has done this kind of "jobs".
