Dream About Tornado And Coolers

I had a dream where I was with my grandma and my mom and we were getting a tornado and these sirens went off and they told us to pack our food and stuff up, we had those coolers that are used to hold ice cream and popsicles at the gas station and my grandma told us to only put the food you eat in the living room in there, I didn't know what that meant so I was putting the stuff from the freezer that I wanted in the cooler and I felt bad because I wasn't putting my mom's stuff in but then I did put my mom's stuff in and I was worried that we wouldn't be able to carry the stuff down and my grandma was saying that I was doing better than my mom and I was thinking about how I always thought it would be cool to be near a tornado but I was terrified
