Quoted from misterschu:
obviously this thread is a lot of speculation, but just going from the survey TWIP did about dream themes, it could also be Goonies, Big Trouble in Little China, Princess Bride, Beetlejuice, Labyrinth, Blade Runner, Predator or Blues Brothers. All on their dream theme results lists, all movies from the 80s.
Beetlejuice is getting rereleased for it's 30th anniversary. I would be fine with any of these themes, but Princess Bride and Goonies would be my top picks
