A glass of Ice Water and Cacti

I was in my Grandmother's kitchen (which no longer exsists.) And was trying to get a glass for some ice water.
My mom was there talking to me and giving me a hard time. Suddenly I was thinking about all my other attempts to have ice water, but the plastic cups had gotten left in various places.
"Don't leave so many laying around and pick some up to bring back" I'm not sure if it was a thought to myself or something my mom was being snide about.
At the same time, I was trying to deal with some dead cacti of my mothers, but the spines kept getting stuck in me.

I suddenly had a glass of ice water and was setting it in my car, It was snowing outside and I was parked around the back of my house where the carport is.
I was trying to back out, but suddenly the car went out of control and I rushed through the neighbors yard (across the street and down a hill) in reverse at a very high speed.
I luckily managed to avoid hitting the house or any trees.
I was working on trying to get out of the area before anything could happen when I woke up.
