Have you ever seen ghosts or orbs when a person dies?

[Bernardo de La Paz]

27. It's not supernatural. It's not dust. It's reflection of some kind

Watch at half or quarter speed when a big circle ( "orb" ) passes over the dark thing on the wall above. The blob alters shape as it crosses boundaries there, as a circle of light projected would. Further, the light dims as it gets onto darker areas.

If they were "orbs" making their own light, they would not dim exactly on the line of sight to darker surfaces.

As to the cause, it's not dust. Dust would not have the circularity or the cohesiveness of the shapes. Dust effects would coalesce into amorphous changing shapes that would dissipate as they moved.

There are a lot of little LEDs with little lenses in room like that full of equipment. But they are often red and green and less often white. The phone itself or jewelry or other things can reflect spots of light. Other sources could be related to the window which might be outside or to another adjacent room. It might be reflections off traffic through small holes in blinds where the cords go through. Or somebody writing on paper jiggling a reflective surface nearby.

What I would do if I were there would be to investigate thoroughly. I'd get close to the wall and watch the light track along it. I'd block light with paper or a board or tablet by holding it in a fixed position away from the wall to block light selectively. Then if "orbs" disappear on one edge going across and then appear on the other edge going away, you can get a handle on the source.

I'd keep fiddling with positions and distances until I tracked it down. I'm used to doing things like that because as a serious photographer I'm always observing light and figuring out what is creating any observations that puzzle me.
