Part of the reason that it is so creepy, is that there is so many ghosts and gibdos everywhere. The more you think about the creepier it gets. The said ghosts and gibdos show that Ikana Canyon used to be full of people. It just ends up very eerie.
I hope they do something like that. Or maybe they could have a few characters or even a whole town that have really dark and depressing backstories. *cough*Majora's Mask*cough*
Maybe those moblin guys showed in the gameplay are dead people who were resurrected by Ganon and sent to kill...
