That definitely be a bit of work since you would need to generate totally new shots.

Honestly I agree with ziggy’s pov about Rey’s connection with the Force being something the slowly reveals itself over the course of the movie, and showing too much at the beginning of the film could go against that. It reminds me that I was initially kind of on the fence about the short Reydream sequence. Even though I liked it, I felt even that might be spelling it out too much for the audience.

Instead of drawings on paper, what if you flipped the shots of the wall that she marks days on, remove the markings, and in its place you could put drawings that she had carved into the wall. At the very minimum, you could have a crude drawing of the island. Maybe that could still be foreshadowing, but not necessarily a blatant sign that she has a strong connection to the Force.
