So I was lurking around on ROTG's Fridge Brilliance page of TV Tropes(because I do stuff like that) and I came across this very interesting piece of information:
One might think that he's interrupted a child's dream, but consider this: dolphins are often used to symbolize fun and playfulness, and Jack becomes the Guardian of Fun. The dreamsand foreshadowed Jack's nature using some creative symbolism.
How cool is that?
There's also a bunch of other cool stuff in there.
Here's a link to the page.
