Morning of February 27, 2015. Friday.
I am on a city bus with my wife although I am not sure of the city or region. It is in a commercial urban area, but is not really familiar. My mother and older sister Marilyn are at the front of the bus (but are both deceased in reality) as well as possibly another sister (who is also deceased in reality). There are several other people on board, most of whom I do not know. The (unfamiliar) bus driver drives around, seemingly on the correct route (as none of the other passengers say anything or complain) but eventually he runs out of gas. He even takes out some sort of case with several thermometer-like meters in it that he uses to measure how much gasoline (petrol) there is or how far the bus can still go.
He drives the bus into a large featureless parking lot near a small storefront in one section and stops the bus and gets out, leaving the doors open. I soon see him talking to another male about thirty feet to the left of the bus in another area of the parking lot. At this point I notice that the parking lot is on an incline (it did not seem as such at first) and the bus starts rolling backwards. I try to engage the emergency break but it does not work. Somehow, the bus starts rolling side over side (even though the incline is seemingly not very steep at all - probably no more than twenty degrees), soon becoming a wreck on the other side of the street from the parking lot. The bus driver does not seem concerned at all and in fact still seems rather cheerful when approaching the wreck.
Most of the bus passengers are still okay with no injuries. However, I notice and remark that one female (of about twenty) had broken her neck and died. She is still somehow sitting in her seat in the same position (though the seat is back at an angle as well as detached now). There is even a bone that comes out through the front of her neck and I feel somewhat sad for her friend even though I did not know these two females that were together. I do not get angry (as I have in similar dreams in the past) and my wife and I (as well as my mother and sisters) are all fine. My dream fades from this point. Elements of this dream were more common when I was much younger.
It is possible in many cases (though not all, including precognitive scenarios) that an accident or vehicle mishap is a metaphor for either the dream being disturbed during sleep, or an approach to the waking process when in an uncomfortable sleeping position. In this case, the bus rolled over, and people also roll over in their sleep. Coincidentally (or maybe not) my wife had a slightly stiff neck when waking.
