I’ve got a few minutes so I’m going to start...I apologize if I get interrupted as I’ll come back tonight and finish up.
This occurred last night at shortly after 5 PM Eastern. I was upstairs in my office which is both my office and my dressing area. The same closest which stores a bunch of personal “stuff” - like boxes of art, personal papers, and old LP records - is also where I keep my clothes hung. And more important to this event, my dresser is tucked in the corner of this room too.
So I was in my office doing something quick and menial - I literally don’t recall what it was - and saw a flash of light while I faced my dresser.
[Editing to pick up where I left off when interrupted during posting six hours ago]
Let me say first before I attempt to explain this away that this was unlike any other light I can remember seeing before. This light was very white; I don’t mean that it was especially “bright”, I mean “clean and crystal clear”. It appeared as something between a flash (short in duration - maybe 1 second) and a sweep (it appeared to move from left to right in front of me.). This light bathed everything which was in front of me including the top of the dresser, some loose articles on the dresser, along with a desk lamp on the dresser, and the wall immediate behind the top of the dresser which also includes a corner where two walls meet.
I have no idea what the source of this light was as it could not have come from behind me...I didn’t cast a shadow on the dresser nor the wall. The flash/sweep of light was uninterrupted and illuminated almost everything at once with just the very slightest delay of bathing the corner and then the second wall to my right.
So here are some of the sources which it could not reasonable have come from:
A. Window immediately behind me as I’m on the second story and the window faces the wall of my neighbor’s home. To send added or secondary light into that window would require someone stand on my neighbor’s roof and direct/reflect it into the window or a flying light source to park between our two houses.
B. Window in the stairwell because that window is between stories, faces my other neighbor’s house, and faces away from the street. More importantly, the way in which light enters that window, as it enters my office, it essentially bathes the walls on the opposite side of the room.
C. The wall, that light hits in point B above, is covered with framed art. But I’ve already tested with a flashlight to confirm that regardless of angle, any reflected light does not reflect onto the walls near to the dresser. Confirmed same is true relevant to light reflective go off of my laptop screen and external monitor.
D. None of the bulbs in the three lamps in my office have blown out. That includes the most likely culprit - the lamp atop my dresser.
E. Not likely to be a visual impairment- I don’t think, I hope not. The light really appeared to illuminate the small area in front of me. For example, the two walls and the corner where they meet were not equally lit - there was an unequal amount of light in those three points.
F. I confirmed there was nothing on my glasses nor was anything ajar about my lenses and frame.
I can’t explain where this bright light came from but it seemed to be originating in the two feet between me and the two walls I was facing.
