A Christmas Carol by Charles Dickens Probably the most famous example of a flash forward is when Ebenezer Scrooge is visited by the Ghost of Christmas Yet to Come and sees his own grave. This is such a compelling scene in the book that it finally tips Scrooge over the edge and convinces him to change his ways.

A flashforward (also spelled flash-forward, and more formally known as prolepsis) is a scene that temporarily takes the narrative forward in time from the current point of the story in literature, film, television and other media.

"fast-forward" is the increase in the speed or the pace (the "2x", "4x", "8x" ) of showing the events afterwards. Unlike "flash-forward", you get to see all the events happening after 'the present' for 'fast-forward', only in a faster pace while "flash-forward" is a big jump afterwards, skipping all that in between.

Think of the flash forward as a teaser: Don't kill your readers' curiosity by giving away everything, and instead let them figure some things out. Use the flash forward as a teaser glimpse of the future, so that you stir up their interest to keep reading and find out how the story can unfold towards that future point.
