When Jack saw a dream that his only daughter killed by a boy ?jack try to find and kill that boy?

The only thing I would add to jacksparrow?s answer is to make the dream more concrete.

You have to let people know her murder is 100% without his action.

To save his daughter, a?father must find the boy who killed her in his dream.

"When a man with Precognition foresees his daughter's death in an accident, He sets off on a dark road to change fate and save his daughter no matter the cost."
