Answer:
Could be Personal Vertigo. Look online for that and see if it sounds like you have it.
i have same problem but mine doesnt happen always. i still dont know what it is but i'm just letting you know you are not the only one with that problem.
you probably have low blood pressure. a doctor can check that with a stand up, sit down, laydown check. i can't get out of a chair too fast or i'll lose my vision for a small spell. a hard sneeze is kind of fun... get your pressure checked (when your calm and sitting in a proper chair)
I have that same problem as well, I ended up checking my doctor today and he said that it could be a number of things, but since I don't really have any visible problems, it might be anemia, so I got a blood test; I'll see the results from that in about a week. Mainwhile, he told me to try to get up more slowly, keep drinking fluids, and get plenty of exercise.
That has happened to me before,only i see line and dots its really really really annoying once i tried hitting and touching them,i dont know but everybodys eyesight can really see something that others see different.It's probably because you know when you spin and stop well your brain moves so it must be that.
his could be a sign of anything. It could be that you are just moving to fast and your blood pressure doesn't catch up with you, or that you might have an inner ear infection, or I knew someone that the problem was that she had to go to the bathroom and didn't know it. But it could be anything even something simple.
have your iron checked just in case but I had the same thing and I took meclizine regularly and it gets better with treatment, but it could be your blood pressure dropping when you stand up too fast or just plain standing up.
