vividness

the vividness of a dream is seen as being tied-in to the time-tense of the dream or montage

a dream which is extremely vivid, say as bright and clear as a sunny day, is placed into the current time-tense or a future time-tense

conversely, a vividness rating of 2.5 or less will be a past time-tense

notes

without exception, so far, all visual content in montages have been 3.5 or higher in terms of vividness

it follows that a precognitive dream that predicts a future event will have a high visual rating of at least 3.5
