That's one of the most bizarre photos I've ever seen. To me it has four separate elements. The first are the series of blue triangular/arrowhead shaped images. Those could be reflections, but that would probably require some multifaceted surface to reflect off of and a light source. The second is the eel-like appendage that looks to be solid, or at least opaque. Then there are the whitish lines, also opaque, that appear to outline the eel-like appendage. Note the bottom one, while matching the lower shape of the eel, is seemingly lagging/displaced down and to the left. Lastly, are the real people/objects we know were in the room. The photo looks to have been snapped with the camera in motion, and without a flash.
I would recommend sending the image to Dr Bruce Maccabee. Based on his C2C interview this past weekend, he does look and comment on images sent to him. His website is
Dr. Bruce Maccabee UFO Research Website, and there is a "contact" feature, although I don't see a way to include attachments. Maybe send him a message first through the website asking if he would look at the photo, then if he responds follow his direction on getting the image to him.
