One Time I Could See Thru Tools Then After That I Could’t Move My Right Shoulder

It could be Arrhythmia here are some symptoms Improper beating of the heart, whether irregular, too fast, or too slow.dizziness, fainting,
:shortness of breath

u probably get up too fast, happens to me but I've trained myself to the point where anything that messes with my eyes doesn't even effect me. I get the vision but It only stays for a few seco ds so I just keep walkin

It's stops for some time but comes back even if u sit done for a little it still happens

A way to stop doing that is to stretch you arms wide out if they are about to fall down that means you need more sleep , if they don't that means you need more rest (as in your body is tired but your brain is not and wants to move)
