To give you a little back round behind this story my father's father (my grandpa) died while my grandmother was pregnant with my father, so my father never met his father which means I've never met him and we didn't have a picture of him until I was about 14. I don't remember this ever happening, but my mother told me about this when I was older.
When I was 3 years old, my mother was getting me ready for pre-school and as she was dressing me I was asking her questions.
Me: "Mommy daddy's dad was married to daddy's mom?"
Mom: "Yes hunny they were married."
Me: "But daddy's dad died right?"
Mom: "yes hunny he died before daddy was born."
Me: "and he's up there right?" (I pointed up)
Mom: "yes hunny he is in heaven."
Me: "No mommy he is up there" (I pointed up)
Mom: "in the attic?"
Mom: "you saw him in the attic?"
Me: "Yes he can't talk to me, but he is really really nice."
Mom: "Oh and he has glasses and a mustache just like daddy right?" (Thinking maybe I saw a picture of my father up there)
Me: "No..." I replied and I described him perfectly.
May I remind you we didn't have a picture of him until I was 14. I don't remember this happening being as I was 3, but my mother told me about it and she said it freaked her out. I believe it really happened because when you're little like that I believe you are susceptible to seeing paranormal activity because your mind has not been corrupt by the real world yet.
