deju vu

I had to ask what is deja vu something we all hear story's about or experienced at least once and might of thought anything of it but really theres alot we don't understand about this human experience that we all are so comfortably enjoying without a care. Some say we can recall things that we never remember happing but for some reason it feels this has happen before many even many times before who knows anyway check out the video comment and rate bad or good and if anyone who watches this video can go deeper on this matter please post and visit www.toymaka.com and get a free pair of brand new headphones when you download Mr.Brooks High School Jams
