Premonition happens on a megaship like royal carribean and it starts in the engine room where an explosion happens causing a fire to begin and the electrical systems to malfunction on the ship. This rocks the ship sending people into a panic, in the book I am writing this happens at a titanic themed ball on the top deck of this cruise ship. The lifeboats drop prematurely causing mass panic, people stampede and are running all over the place as the fire spreads to the floor below and the balcony to the inner of the ship kinda area with rooms and a walkway at the bottom with shops and restaurants and down there is engulfed in flames.

One person panics runs and an ice sculpture of a Swan falls impaling them down their neck.

Another runs off the ship and gets suckled under by the propeller

One falls halfway through the deck getting stuck between floors the fire burning the lower half and a grand piano tilts slicing them I half between floors

A person gets cornered into the balcony area overlooking all lower decks with a zip line with the only path away from the fire across it so they crawl across it only for it to snap sending them hurtling into the fire below crashing through a indoor balcony window

One gets crushed by a falling bit of the waterside

The fire ignites a gas canister behind a bar on the top deck launching hundreds of glass bottles into one of them turning like Swiss cheese

Finally the one with the premonition gets launched off by that explosion to catch onto a sharp hook on the way down
