ghost helps dad find girl in a game of hide and seek

This is a home taped video of a father and daughter.  The dad found the girl at first and decided to play again.  He was looking all over the house to find his daugther.   Finally he enters the same room where his daughter was hiding and you could see a hand like shadow pointing towards where her daughter was hiding.  There seemed to be shadows moving as well.  Do you think it’s the lighting which caused that effect or was it the ghost helping his father find is daughter?
