Hi I would be happy to help assist you in understanding your dream. It sounds as though you have a lost connection with yourself and or God. Falling asleep at the wheel is showing how perhaps you have fallen asleep spiritually. Running over pedestrians is showing how perhaps you are just moving forward in your life in a zombie like state not fully aware of what is taking place. You realizing you had passed away is showing a spiritual death. Putting God out of your life? Perhaps this path you have been on was by your choice? If you have anymore questions feel free to ask.
