A man who is awake in the open field at night or who wanders over silent paths experiences the world differently than by day. Nighness vanishes, and with it distance; everything is equally far and near, close by us and yet mysteriously remote. Space loses its measures. There are whispers and sounds, and we do not know where or what they are. Our feelings, too, are peculiarly ambiguous. There is a strangeness about what is intimate and dear, and a seductive charm about the frightening. There is no longer a distinction between the lifeless and the living, everything is animate and soulless, vigilant and asleep at once. What the day brings on and makes recognizable gradually, emerges out of the dark with no intermediary stages. The encounter suddenly confronts us, as if by a miracle: What is the thing we suddenly see-an enchanted bride, a monster, or merely a log? Everything teases the traveler, puts on a familiar face and the next moment is utterly strange, suddenly terrifies with awful gestures and immediately resumes a familiar and harmless posture.
— Karl Kerényi
Kerényi is describing what happens when the ego's sorting function fails — when the machinery that divides near from far, living from lifeless, familiar from monstrous, simply stops working. Day is the time of that sorting; night withdraws it. What you are left with is not chaos exactly, but a prior condition, the condition before the distinctions were installed. The soul in this state is not confused. It is exposed to what was always underneath the categories.
The traveler's unease is specific: things put on a familiar face and then become utterly strange, terrify and then resume harmlessness. This flickering is not a failure of perception but a disclosure of how perception normally operates — by suppression, by settling the image into a recognized slot before it can be anything else. Night removes the slot. The log might be a bride or a monster not because you are seeing poorly but because you are, for a moment, seeing without the apparatus that forecloses the question.
Hermes governs this territory — the guide of souls is also the guide across thresholds, which means he is always the figure who moves through the zone where categories have not yet hardened. What Kerényi catches here is that such zones are not exceptions. They are what the soul inhabits when the day-world's guarantees are temporarily unavailable, which is more often than we tend to admit.
