Hi, I am from England and my grandfather is my guardian. He often does what granddad's do. You know, drives you mental but at the end of the day you love them. My experience starts, in fact, with my sister. She was casually speaking to herself, aged 3. When my mother heard her, she asked who my sister, Toni, was talking to her. My sister replied "It's the old man, sitting on the end of my bed. His name is charley, he often talks but he mostly listens". Seen as my sister didn't have many friends it wasn't really an issue. About 5-6 years later, I was also in the same situation. I don't remember ever talking to myself but I do remember an old man but I don't remember what he looks like.
My mom got a similar answer when she asked me who I was talking to. My mom only really registered what had happened until she was in bed. She has often felt a presence in her room and sometimes feels him sitting on her bed.
May I tell you that my grandfather died when my mom was 2? Well, I was 2 when we first discovered our friend. I also feel very safe when feeling his presence and he often turns my music down. Isn't this what a Granddad's does?
It was my auntie that first came up with the connection, she believes in the spiritual side, as do I.
Take care
