Man Behind Me Ghost Picture

Genia sent us this ghost picture of a head beside her. Is it a man, or camera created through movement? You decide...

"Attached is a picture of me that I took when I felt like something was behind me. I was really surprised to see a figure of a man in the picture behind me. Is it a ghost or an angel? My dad said it looks exactly like my great grandpa,whom I never met. He passed away at an early age from a heart attack."

Is this a man beside or behind her?  The head looks male with short hair.  Sometimes camera movement will capture what appears to be multiple images.  Is it a ghost?  You decide for yourself...
