When we think of dreamlike films, or dream sequences within films, we inevitably think of the expressionistic style filmmakers often use to signal a dream state -- but of course real dreams do not present themselves in that way. We might, in a dream, find ourselves at home and discover a previously unnoticed door opening onto a previously unsuspected wing of the house -- but that wing is not appointed like the cabinet of Dr. Caligari . . . it is as convincingly real a place, in the dream, as the actual house we know.
