Dream

has anyone had this happen? where you get a strong feeling of dejavu but it's a strong feeling as if your body is reacting to something? today i had a moment like that. and i remembered a dream where i was doing what i was doing at that moment.About 2 months ago when i first applied for the job i had the dream.3 years ago i had a dream where i got a call from the school saying i had failed my exam, math was never my stong suit but that semester i had worked hard but wasn't getting anywhere. and after i had the dream.. like hours after i had woken up i got a call from the school and it got the news that i failed my exam.Those 2 instances aren't the only times, i know that i've seen into the future before in my life many times, but after the insident with my Math exam i started to keep tabs on my dreams... when i was a kid i could remember my dream from start to finish... but as i've gotten older my childhood dream are more vivd in my memories but my recent dream slowly disapear soon after, i can remember what, but not who, where, why, and when.
There are dreams that stand out, not that i have reoccuring dreams but just elements... i have dream where im with a group of people fighting for our lives trying to save ourselves from some unseen threat... when i have those dream there always different but slowly they've been getting more and more graphic as time draws on.... who know what it could mean.
