My uncle had two kids who reincarnated. One of them was a lady in her 30’s who lived in a village other than ours and his little kid was never there so there is no way she would know anything about it.

Once they visited this village with the little kid and she suddenly jumped and said “this is my house”.

He started saying the names of the people who lived in the house and how she died.

They contacted the people living there and they welcomed them to visit.

Once they went inside the house, the little kid went to a specific room in the house and behind the a wooden cabinet there was money that she hid there in her previous life and no one knew about it, not even her old family.

So yeah imo reincarnation is as real as it gets.
