Thanks to Kousuke for sharing this video clip
This video was taken during a family gathering in summer. An old man wearing a kimono was captured sitting at the sofa looking at them. When the video was taken, she confirmed that no one was sitting on the sofa. The spirit left a cup on the floor. Her mom noticed that and feel something wasn’t right as they do not have any of such an old cup. The girl then preview the video and they were shock to see an old man sitting just in front of them. Her father said most probably he is his ancestor who died centuries ago.
