I was driving and my daughter and I just came home from going shopping. As I was letting her out before I drove the van into the garage, I had pushed the garage door opener and it was just about to come open when the van jerked before she could open the door to get out. The van accelerated and propelled us through our own garage into the house, it veered to the right. This happened at a blink of an eye but I screamed. I have my foot on the brake, I don't know what's going on.
