Lucid Time!

I used to have an aunt and uncle that lived in a sparse neighborhood near the edge of our town. But they moved to Alabama when I was about 8. This dream supposedly involved them.

My parents told me they were taking me to see a new garbage dump that they had put in where my aunt and uncle used to live. We drove along this country road. It was summertime and the forest was green and lush. We finally arrived at their neighborhood and got out of the car. I was with my parents and some other girl I didn't know.
I got out and started wading in a pond.
"It's a shame isn't it. Ever since they put in the new garbage dump, this pond is polluted and the fish are dying."
I looked into the water, and I could see the sandy bottom and fish swirling around.
We waded along the shoreline until we came to a clearing in the woods.
The stranger girl beat me there. For some reason, she looked very hazy. All I could make out was that she had black hair.
The ground showed evidence of a heavy vehicle, and there was a rather small hill. Supposedly, it was the garbage dump, but it was quite small. Perhaps four feet high, and ten feet at the base. If there was garbage, they covered it over with dirt.
The stranger-girl I was now alone with kept talking about the garbage dump. I just sort of sat there quietly so that she could let her thoughts out. She seemed so sad.
