Vivid Dreams Remembered

I awoke this morning and remembered some dreams that I had. The one is a repeat that I have had many times before and don't know exactly what it means but can probably guess. I am driving my truck without a trailer (called bobtailing) to my Moms house (where I grew up) but when I get to the drive the truck has no brakes and won't stop. So I have to pass it up and I keep pumping the brakes and pressing them as hard as I can to the floor but it doesn't seem to slow the truck down so I pass the house and try to stop as I am going through town but it still won't stop. This time town had new buildings and different things done to it than in the other dreams. My theory is that my life is out of control:))

The next part involved two machines. One somehow drilled and ate it way into the side of a mountain and made a hole about 3 or 4 foot square and would do something with the rock and dirt but leave a line of coal (I guess, maybe gold)that it dug out laying in the path to be picked up later. The other one looked to be 8 feet tall 16 foot long and was sort of like a bush hog on its side. There was a man who stood on the top of it, the whole thing hooked with a chain on each side and suspended from a crane sitting atop a mountain. the guy was standing and holding the chain and making it swing wherever he wanted it to go. It was called a rock facer and he would swing it in to the side of the mountain shaving all of the rough edges off of the mountain side. But it cut and ground through everything like it was grass and weeds. The shavings just fell down the side and gathered at the bottom. Weird!!!!!
