short for dub-in,
having the
manifestation of putting, unknowingly,
perceptions which do not in
actual fact exist, in the
environment. (It is a
phrase taken from the
motion picture industry, meaning to record dialogue and various sounds and then integrate them into the film after it has been
shot. This is done for scenes where the original recording is faulty, for scenes where it is simply more convenient to add dialogue and other
sound later, and for films playing
abroad which require new dialogue in the
native language of the
host country.)
