I had two accidents within a month of each other and that was before I knew about dissociation or was in trauma therapy. My father in law (someone who was a like a father to me) was just put in hospice and my mind was on that and my unethical T. I rear ended a car both times, on the road I live on both times, both while coming to a stop at a light. While I did apply the brake and was almost to a stop, my mind wondered at that moment and I hit the stopped car in front of me. BOTH were those PT cruisers. When I am upset or coming from therapy, I have to make sure I am grounded, and a good trauma therapist will help you with that after a session. But I have to make sure I am constantly present and think of each driving actions like you did when you first learn to drive. I make sure I am not too warm, and I suck or chew on something very sour or hot and spicy. I am thankful I am not like this most of the time, but now I can sense when I am and I try not to drive if at all possible if I am feeling this way.
