What I personally find intriguing about this photo is that normally "ghosts" don't show up in photos like this. There's more of a shadow or a mist usually that makes up the form. This is how I see spirits in real life. This image reminds me of how my grandfather showed up at my house on thanksgiving a couple years ago. Like an imprint, as if their form is embossed over the scenery. Which leads me to believe this person is a visitor from the other side. I see a man with short, wavy hair, casual wear like a hoodie and cargo shorts on with low sneakers like vans or etnies.
