Lucid dream?? Cars in back yard

Date: 3/31/2017

I was in the basement with dad. I head a noise and looked outside. 2 gigantic cars were coming down the hill in the back yard, one had these attachments all over it. I immediately realized this wasn't something that would happen in real life, and I turned and sprinted to the bathroom. Looking in the mirror I did the nose test. I plugged my nose and tried to breathe and I still could. This is when I knew for sure I was in a dream. I was trying to stay calm as possible and walked outside. I was thinking how I could do anything but I didn't know what to do. I jumped up and hit the rim of the basketball hoop which was really high. There was a bunch of people I knew and I made my hand into a gun and started shooting them and they all started dropping. Then I went in the yard by the tree and looked at the clouds and jumped up and tried flying a little then suddenly the dream ended
