Have you seen ghost of someone you know when they're alive like grandfather, fren's father etc.? Are they aware of you?

Can you see ghosts in picture or TV?

If you take photo with ghost? Can you later see the same ghost in the picture

TS already said

"
my uncle sees the same thing as I do. So we often look at the same areas when these things passed by, mentioned their features to each other,etc..

"

How to explain they both see ghost in same area and both notice at same time when same ghost appear.

Not that i believe ghost until i see one myself. I just keep an open mind and see.

TS already say he live a normal live and just sharing only.

There is known known and known unknown.

Science cant definitely disprove the existence of ghost just as there is no scientific proof of ghost.

For now it is a known unknown until more proof, why are you so adamant about ghost being fake? I personally accept it's a known unknown for me. Not everything have to be false or true.

One of the values of a scientific mind is open mindedness, the willingness to change given new proof/discovery and accept that there will be known unknown.
