Dream About Fishing Boat Ptsd Tornado Fire Pit

I was in a fishing boat laying down. My fiance woke me up and i had a ptsd flashback i thought he was my ex. He walked away and i saw a tornado forming and all of a sudden my boat started moving so fast. I couldnt hold on i kept jumping up because it was going so fast. The boat stopped under a bridge. there was a teen girl there that asked about a prom dress. It was silver and blue and so pretty. She had a flip phone with a silver and blue case with a penguin on it. I was then in a big house with my whole family. My grandparemts were on a huge sectional couch. My twin cousins, my uncle, my fiance and i were sitting on a couch behind them. My grammy told me about children that died in an explosion. I built a chamber made out of glass and wood. I put a book of the explosion in the chamber. I turn around and I saw a big fire pit with children gathered around. Each of the children had a long rope in their hand. They each had to light the string on fire. The first kid put the string in the fire. The next kid touched their rope to the first kids to light their string on fire. Each of the kids did this until the last kid. The last kid threw an object into the fire pit and it exploded. All but 2 children died
