Probably heat waves. Near windows you can see their shadows, so to speak...same things that cause mirages on the streets on hot days, as well as that
watery look on the top of cars on hot days.
A neat effect caused by air pockets significantly warmer than the air around them. The excited particles are moving enough to distort light.
No it is more like heat coming of tarmac in the summer. But it clearly was not the air but something else. Another poster here talked about
distortions. I think it was space-time itself being distorted and maybe not so much those things being energy waves. Really, I don't know what they
were and I never tried to interact with them. That is actually a shame, it might have result in more knowledge.
You know I have noticed recently that I see these "fluxuating" circular type waves in the center of my field of view.They look similar to heat waves
on the road.It is like they are 'targeting something',lol.Also I can see many black spots floating in air with an occasional larger white
colored(energetic looking) spot.My first thought was an eye problem but then I thought about it and these spots look a lot like particles.........???
