When I was young maybe around 6 years old and my sister was 3, my grandma and I had a very odd experience which I don't remember because I was so young but my grandma remembers it clearly.
It was a day that she came over to take care of us. I'm guessing that our parents were out at the time. She was changing my sister's diaper and I had wondered into the kitchen. She had told me to get back over where she was several times but I didn't come back. It was the last time she looked up when it happened.
She looked up from changing my sister's diaper when she saw me next to the knife drawer. Next to me in the air was the transparent head of her dead mother. She had died when my grandma was young. My grandma said she was in shock of course and I looked at her and said, "I was only talking to her."
I don't remember any of what happened at the time but, because I'm a huge paranormal geek, I had to ask my grandparents when they came to visit.
I believe that the reason that happened was because she was trying to tell me not to open the knife drawer because I would get hurt and my grandma was busy so she wasn't there to help.
I would have never known that I talked to spirit before if my grandma never told me!
