when there was a nuclear disaster

I had such a weird dream last night. I dreamt that this nuclear reactor near us, like, had a meltdown. I woke up (in the dream not IRL) and everybody had burns from it on their face. It felt like a sunburn but it was numb to the touch. I was apparently living in this huge group house with my cousins and my grandmother and a bunch of other people. Me and my cousins and my grandma was all right but a lot of people (mainly the people in the bedrooms on the upper floor) were dead. I knew these people in the dream but I didn’t seem too upset over it. We were mostly trying to calm down Cath who was in hysterics.
That’s all I remember about it. I didn’t sleep well last night!
