I've noticed this effect after a really good movie or book. I can almost "feel" my brain thinking, ticking over and assembling meaning from what I've just seen (and can even sense "eureka!" moments), despite having no conscious awareness of the thoughts themselves (just TV static). It also seems to happen more with foreign films, perhaps as they require an extra layer of subconscious analysis to parse the message by separating it from its cultural shell.
