Hey everyone, so today i was cutting the lawn and looking straight ahead for a long period of time. When i looked up after a while and focused on a tree in the distance, everything else in my line of sight that i wasn't focused on began to move outward and in away from me. It was the scariest sensation. It was like everything was moving away from me very fast. I thought it was because i wasn't wearing my glasses, so i went and put them on and the same thing occurred. This has never happened to me before. Does anyone have an explanation?
