i believe that telling the future in dreams is very possible, because i have sorta what you could call ESP, or extra sensory perception (i can, at random times, tell the future).
I’ve had deja vu three times over the same thing. The original place I saw it was a dream. I’ve also had deja vu for 20 seconds where the current events unfold just like i’d seen them before.
ok so the weridest thing happened to me last night.
well first it was 10:00. i had a assignment for school due the following day. so i stayed up till about 2 am. was really confusing.
then i decided to get some work done and stay up all night. so i cleaned my whole room. did some more homework. played some call of duty.
then its about 5 ish. im kinda drifting off. so i decide to lay down. with MP3 player in my ear. (i can never fall asleep if im listening to music) but yet i fall asleep at 5:52
i wake up at 6:20
so about a half hour of sleep. the weird thing was. either the dream or the HI
was a black in white video thing. of people doing something. i actually remember dreaming it (or thinking it, i was way out of it)
but in school. we were watching a video. and that 5 sec clip came on exactly the way i saw it. no dejavu. i SAW it. when i was falling asleep. when my mind was just between reality and dreaming (maybe sort of OBE)
well if it was the sleep deprivation or the MP3 player. or just me thinking about school right before i fell asleep. (and who knew it would be that following day)
share your experiences (not deja vus) but seeing the future. sorta thing. and what you think caused yours (or mine) i would love to be able to see the future. (i have diff perspective of the future) you can only see things that ARE going to happen like. and earthquake. pop quiz. or high probabilities of something.
I’ve seen into the future once. I was dreaming I was exploring Willy Wonka’s chocolate factory and then the next day I found out our school play was Willy Wonka! 
Well, im not sure if you can see the future in a lucid dream, but i strongly beleive you can see the future through astral projection or by having an OBE and simply teleporting to the past or future. I actually read about this guy who wins the daily lottery because of astral projection. So maybe you can try this, hope it helps.
