How to rewrite part of rapunzel in dream sequence

One way you could possible do this is by, when Rapunzel is remembering her child hood, so her parents. as in the movie she has a flashback but instead of a flashback you could turn it into a dream sequence. you could also make another dream sequence about flin rider. as you probably know, Rapunzel has a crush on him, most likely making her think more about him, or dreaming about him. this one you could also make it humors, since we all know flint is quite a charmer.

hopefully this helps you!
