What does my past life mean , is it real and who was I ?

At the age of two ish (so I hadn't been talking for long) I told my mum about my 'past life' . I said I'd taken care of the church and cemetery , I'd told her I had a border collie dog named zena . I can still remember some small bits of my before life , the church I looked after I can picture the inside of it perfectly , lots of small details and everything . I can remember the old oak tree in the grave yard and I remember myself putting some dark red flowers by a grave . I remember the railings that went around the yard and I can see the field with all the graves in it like it was yesterday . I never saw what I looked like myself and I don't have a clue what my name was , but I feel as if I was quite old , late sixties. When I was two I moved to a town neighbouring the town I was born in , I have seen a tiny bit of the outside of the church there , but only a tiny bit . I know myself that the church in the town I moved to is the one that I looked after in my before life . I can remember it all so clearly but it seems I can only remember a few minutes or short clippings from my past life and when I try to think back they are still the only things I can remember . Also when we moved again to an old house in a different town at the age of about five , I saw a ghost . I can't remember it myself but I was stood with my mum and asked her who the woman going in my room was , she couldn't see anybody , only I could . But the thing that sticks out most in my memory is a stained gl window in the church . I'm just hoping to find out what any of this could means , if it does mean anything that is . I'd be very greatfull to hear anything you have to say about this . Thankyou :) oh and I'm 12 at the moment so it's around 10 years since telling mum about my past life even though I can remember it now .
