Yes, the other factor to pay attention to is the action within the dream.

starlite, you were driving (suggestive of control, of being "in the driver's seat") along a road (your chosen path?) when suddenly you are brought to a halt by an enormous and overwhelming body of water that is shaped like a triangle (do you have a similar "triangulated" relationship in your life?).

Either way, the dream seems to be telling you: You need to deal with the "water" and you cannot not do so from within a car (or your usual method of transportation/delivery). Maybe you need to switch to a boat for the next part of this journey.
