Recalled White Room as Visual Overlay

In June of 2026 one night when I was unwinding for bed I was sitting in my living room when for a couple of seconds my entire living room transformed into a white room. I was sitting straight up on some sort of metal table and in the room, there were various other metal tables scattered about. Far off to my left stood what I believe was a tall orange, beige colored grey type of being performing some sort of work at one of the tables. Behind the on the wall were various metal devices and tool stations. Before I had the chance to react or turn my head to look fully at the being the visual overlay vanished and all I could see was my living room just as it was.
