Ok, I don't know I just found this out. When I was looking at a bright white screen on my computer I was seeing some auras. I was also looking very closely(like 3-4 inches gap btw my fave and screen) because I was trying to remove a piece of stuck dirt on my screen. I did not saw that aura anywhere else and even on the screen if I stepped back and sat to my normal position. Or even if I changed the screen to a darker colour. Why did this happen.
