Why does this happen? (read below..)
when i stretch i feel dizzy & my vision messes up, like i cant see perfectly because its blurry. i use to yawn real big and my vision would mess up also, id see like gray/blackish on the perimeter... if that makes any sense :/ not tunnel vision but idk its hard to explain unless youre going through the same thing. this hasnt happens much lately now that i think of it but i still am curious, and i dont wear glasses and or contacts.
