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.
