Dream in a Bus

My sister had a dream in which the 3 of us (me and 2 sisters)where heading somewhere but the road was an uphill and was along the ocean. At one point, my sister said that we got somehow distracted and managed to get out of the bus to watch the view. Then, we realized that the bus had left us. We run to catch the bus and realized that the bus was riding over sand and we were running over the sand as well. At the end, we were able to catch the bus.
