With some people, they have this tendency to fall out of reality and get stuck into a fantasy world, which may seem perfect, but eventually starts falling apart, because they've been away from the real world for too long. "Well you built up a world of magic, because your real life is tragic" this is the fantasy world that people create and escape to, because of the tragedies in their life that they can't handle. "Go get your shovel and we'll dig a deep hole to bury the castle, bury the castle" implies that it's okay to step out into reality, and bury away the fantasy world, because the truth lies in the real world, which is where you should be... Most of the time.
