So far I've been able to experience hyper-realistic imagery, so real that if I had took a photograph of it it would be almost indistinguishable from reality. However I haven't been able to keep that level of realism for more than a couple of seconds, plus either I don't remember the transitions or my brain just skipped them and made the dream a slideshow without me noticing it.

So, how realistic can lucid dreams get? Of all of you who consider themselves experts of the art of lucid dreaming, can you keep a dream 100% life-like for, let's say... an entire minute?
