Seeing Ghost?

Hello people.
My mom and i were discussing about many things about my little brother.
She told me that he plays with his grandfather sometimes. (He never met him, he past away when I was about 8 years old. I'm 22 now.) She told me that one day a picture of my grandfather fell on the ground when she was moving a picture frame that was placed high up.
He saw the picture and said
"Oh he is my grandfather we always play together."
My mom replied with
" that's is not your grandfather Faby." Just to see what he would say.
He said
"Yes it is, we always play together and he told me." My sister had her hair standing Lol and asked him if he wasn't afraid.
He replied with
"Why would i be afraid of my grandfather?"
My mom would later observe him while he would play alone and she said to see him talking by himself sometimes.

I was wondering if someone would take a look at his chart.
Please and Thank You .

Interessting. Can you give the time of the events and the birth data of your grandfather?

the first thing I notice is mercury opposed to Uranus. this can give access to the astral plane and hence seeing the departed.
with the Neptune/pluto midpoint conjunct the node, there is again a path way to spiritual connections with the dead.
a composite chart with the grandfather likely would make things clearer .
