" Come you near or go you far, light from candle or flick'ring star? See what you will, or so you think, but is water sweet before you drink? Who can know of truth and lies? When can a man believe his eyes? Suspect what's known to mortal senses, for our nature vaults all mystic fences, that stand between that which is and seems, and back we are to truth ... or dreams. "

― Raymond E. Feist , Faerie Tale
