People always ask if I lived past lives why cant I remember them, the answer is simple it is a protective mechanism by the brain cause you need to remember that you died many times in your past lives and if you where to remember a yourself dying over and over again your mind could not handle it and you could go insane.
But fragments of those deaths and past memories lingers in your brain, you are afraid of heights you where push off a cliff or something similar, you are uncomfortable in deep water you died from drowning etc, do you sometimes meet a person and you dont like the person and you cant explain why, its because in a past life he was your enemy, and sometimes you meet a person and you both just click, in a past life that was your friend.
