These are interesting questions. But has no one here ever experienced
an after-image of a dream image? I have. The brief retention of
optical stimulation that results in a visual after-image when we look
at a bright object, for example, is, I think, a fairly well-known and
well-understood phenomenon -- a sort of brief persistence of vision.
What is interesting is that when awaking from a dream (eyes still
closed), I have more than once experienced a similar "picture" in
closed-eye vision of what I was last "seeing" in my dream. This would
suggest that images are formed not only by optical stimulation being
interpreted by brain, but also by brain activity stimulating same
optical nerves -- in other words, in reverse. Also, when people are
extremely sleep-deprived, they can begin to hallucinate, right? --
basically dreaming while 'awake'; "seeing" things that are not there.
So I think images in dreams do involve both memory and optics -- and
that the content is not just "post-production" as Saul would have it
(thought there does seem to be a certain randomness to dreams, and
obviously we do constantly select and interpret amongst everything we
hear, see, think, etc., and so undoubtedly do this in response to our
dreams as well.) . . . But as far as images are concerned, what seems
to me harder to grasp is an image in thought (while awake). For
example, if you right now bring to mind a friend's face, in what sense
are you "seeing" it? . . . Some similar optical memory process, I
guess, but entirely elusive.
