This is so obviously exactly what it appears to be! A man is kneeling on the floor; a baby lies beside him on the floor, and a shaft of light from a partially opened door, or window shine over the baby!
I have seen a few of the photos that have been posted by the same person with what appears to be the same streak of light in the photo. I have to wonder if this camera has ever been dropped before and there is some type of infraction coming from a damaged lens. Please have your camera lens checked and see if the streak goes away if you have it checked and it's in perfect condition than I would have to agree there might be 'something' going on here I mean there.
