a montage is a sequence of images with or without motion in them which last for a half of one second or less and can be as long as one or two seconds
there hasn't yet been an exception to the rule that montages have the same time-value whether they occur in dream-time or awake time
montages can be controlled by the person in that the images/sequences can be of the persons own making
moving images can be replayed and still images can be "freeze-framed" which enables a person to take in the detail
montages are categorised first, by the number of image/sequences they contain...
two or three images = mini-montage
three to ten images = montage
ten to one hundred images or sequences = mega-montage
one hundred to five hundred = maxi-montage
more than five hundred = montage-minded
one times two times three times four times five times six times seven times eight times nine = 300 000 + categories of montages !
