Yes there is. Reminds me of a scene from the flick Poltergeist.. the "haunted" finally get some scientists in to help the family.. spectral light goes whizzing by.. Scientist expresses awe, the family member says: Hold on, they usually travel in pairs -- there'll be another one... and another goes whizzing by.
That put a grin on my face to step back and look at the big picture and what my face must look like as I follow all these stories. Nothing much has, in these stories, put a grin on my face, except that : )
