Lighting (ghost or halo)

I really like how the lighting is in this photo and another that I already posted. I don't know what happened because I was indoors, in the house, and I wasn't by a window, but that light is pure white and looks like sun or something. The lighting in that room was the same yellowish low light where I took the photos of me with the painting of the cat-tails. So it's a very bright white light that came out of nowhere or ? I wish I knew how it happened. It looks other-wordly. I sort of thought, like a ghost or apparition or something. Maybe it's my halo. The halo only my son and a few others ever get to see.
