Dream About Thunderstorm And Grandpa

I had a dream that it was thundering badly at my house and it was a bad strom I looked outside and I saw a huge thunder bolt and then I went back inside and watched a bit of Disney then I went back outside ane I saw this beautiful scenery it was like a sunset but drizzling and then I saw that the fire hydrant was completely broken and it was shooting water straight up and I saw a powerline down and then I saw a car scrape another car and then a person went into my moms car and just took her lemonade and left the door open and drove off which was weird so I get in the car and I was talking to my mom telling her what happen and then my grandpa he sits in the car but my grandpa is dead and I was like what is he doing so I lock the car but he starts driving and I call my mom letting her know and I try to get him to stop at a gas station or somewhere but he just continues driving and no matter what I brought up he wouldn't stop.
