Space is an integral constituent of the self. Our psychological sense of selfhood has a spatial dimension which we recognize in our feelings of comfort or unease in response to the places that we visit and inhabit. At night the world of clear and articulated objects finds itself abolished.

Night makes us aware of the spatial nature of our being, since it readily abolishes the distinction between "us" and the "beyond," between the demarcating limits which the imagination creates for the self to join us to the world, while still retaining a sense of our separate identity. The dark makes the familiar unfamiliar and threatening. The monsters that lurk in our imagination come out to haunt us.
