Ghost? Caught On Camera New Zealand Hauntings Unexplained phenomenon paranormal spirit

I was taking photos of a clients house for Insurance purposes. Later when I was uploading the photos I noticed the legs in one of the photographs. This was pretty upsetting since I was alone in the house(or so I thought) when taking the pictures. I found out later that the owners wanted to move out as they believed there was the ghost of a small child in the house. WTF??????
