I've seen many of these types of images, I also am a photographer, and what that is, is either:
1. Picture was taken behind glass, flash reflection distortion.
2. Lens slightly dirty, (like a streaked fingerprint) and when the shutter shot, it created what many call a 'anomaly'
3. Was the sun in front of you? Could have been a solar flare (I doubt it though)
4. It's a ghost, and you're in deep shit now!!

j/k.. I seriously doubt that, here, look at these, each one isn't a ghost. they are Camera anomalies:
below is a reflection on the furnature
Below is Snow.. prolly taken with a slow speed shutter:
BUT.... Below is something scary.....
Look BETWEEN the two guys.. see the demon? (Light effects..)
But Below, I cannot explain as well.. the baby is LOOKING up at this.. maybe babies can see stuff we can't???
