Dream About Flooded Garage

i woke up from a nap and went to look im my garage at my dads house and the whole outside was flooded and the garage and my little sister had a floaty and was trying to swim and i told her to get inside and i grabbed her and called my mom scared and she said that everyone that morning went to my aunts to be safer and i yelled and asked why she left me and my sister and she said because i was sleeping and she wanted me to watch my sister she eventually came and got me and we teleported to my aunts and i sat on the floor at my aunts house and my mom was like sarcastically asking if i was fine now and i was upset with her and she said she didnt care that i was there by myself scared and alone with my little sister
