How important is what you see when you faint?

i fainted last year and saw visions of being on a merry go round and also a future me jumping into a lake off of a wooden diving board thing. when i was jumping i looked about 30 years old, i'm 19 now and there was a man (presumably my husband) and two little girls (maybe our children) jumping with me and we were all splashing around having a good time. how important is what you see when you faint? and have you ever experienced anything that later came true that you saw while fainted? also have you had any interesting visions while being ped out?
