Bulldozer

[junamiller2002]

I dreamt that myself and daughter were walking along a highway, when a HUGE Bulldozer swung around on a piece of bare land, and started to lower the shovel. The driver did not see us below, and we screamed and started to run out of its path.

It picked up a full shovel of dirt and then swung again in our direction. When lowering the shovel it just missed hitting my daughter. I screamed as she ducked out of the way.
We were horrified.
All of a sudden we were in what looked like our home.(Not where we live at present) I went into the bathroom, and was sitting on the toilet thinking about what happened, when I heard a knock at the door. A male voice asked"Is your Mother home?" Mariana came to the bathroom door, and said Mom someone wants to talk to you, and I said I"M IN THE BATHROOM, give me a minute. I came out of the bathroom, and now I am in a slip. And I want to cover up. So I am looking for my wrap. I take one out of a drawer, but my daughter gives me one and says this one is better...take this one. Standing beside her is my sister, whom I have not spoked with for years. This woke me up...seeing her.

In the context given, the bulldozer represents a person or event that is or has been quite overwhelming.

This does relate directly to the sister that you mention showing that she has been dominant, careless or flat out dangerous to you...at the time in your life that you lived in the home pictured (if you have never lived in that home in real life the house represent you, the person that you are).
Your sister has affected you to the core in a negative way however, there is innuendo that it may be time to again make contact with your sister. Start with a clean slate but be cautions. That is the indication.
