For those of you who think ghosts are terrifying, I think you need to check out Aurelio Sanchez's 'Finisterrae' photo series. It depicts two traveling ghosts and I can't think of anything more awkwardly adorable than these two out-of-place friends.
Of course, I'm sure you're not afraid of the white sheet ghost, but we'll deal with scarier paranormal creatures at a later date. Right now, immerse yourself on the journey that Aurelio Sanchez takes you on. It will get you in the mood for a fun Halloween holiday.
