Bulldozer — a reflection guarantees the destruction of obstacles. The need to be prudent not to "bulldoze" what is valuable. The need to stop being a "bulldozer".
The bulldozer can mean clearing of a way and destruction of barriers. Go forward. Simply do it!
To see a bulldozer in your dream, suggests that you are feeling pushed away from what you want. Or that you are being diverted away from the path toward your goals. You may be feeling helpless and bullied. Alternatively, it suggests that you need to organize and clear away the clutter in your life.
