The bed sheet as metaphor for the continuous field of consciousness.
"Bed sheets serve as an almost universal accessory to elemental manifestations of desire. Also amusing is the thought that bed sheets are horizontal in the dark and hung vertical to dry in the sunshine. Nature is horizontal and culture is vertical, and a patterned bed sheet introduces the whimsical curlicues of the social imagination into the horizontal biological realm. The bed sheet is also a metaphor for the continuous field of consciousness."
