Go to an eye doctor immediately!! it may be a tear in your retina... you need to have that treated asap!

It sounds like you're experiencing a migraine aura, but you really should get it checked out with your eye doctor ASAP to make sure that it isn't a retinal detachment.

It's a visual migraine.  I get them too. Painless, fortunately. Mine looks like a neon alligator flashing on and off.  My sister has them, too, and she said that if you try to examine the zig zags, you will see they are made up of images of items that you just looked at.  She's right! I tried really looking at it and the zig zags do contain images.  Interesting in a wierd way.

I have the same problem dude. I'm thinking you have what is commonly called 'floaters', that is, you have small particles floating withing the fluid of your eye. You see these lines and dots because they float over your retina and block light, casting a shadow. Usually this is a non-issue (nothing to worry about), and only appears when looking into a bright light (I.E. a microscope) or staring an uncommonly bright image, or paper. It could be a sign of retinal detachment (a very serious issue) if it is  persistant (constant), or distracts you from everyday things such as driving, or working. \n\nIf you are really worried, check with your Eye-Doctor or Physician, they'll tell you if it is completely harmless, or if you should take further action

Hmmm, could be different things.  \n\nGenerally flashes can be one whole thing.  One way this happens is when blood is rushing out of the head to other parts of the body(Like when someone is about to faint).  Standing up really fast after sitting a long while you can see dots of light floating around like a cartoon character would see stars after getting hit on the head with a mallet.\n\n"Floaters" can be a whole other.  Whenever you stare at bright light, temporarily part of your vision will "turn off" to protect itself.  Then you'll have a little black spot(or a while spot in the dark) floating around like bug.  Sometimes they can be permanent(in extreme cases, like staring at a solar eclipse), but usually for other medical reasons.\n\nThose are just examples, but there are lots of reasons why you can see odd things in your vision.  For example, I have strabismus(crossed eyes).  When an eye tries to jerk to one side really fast I sometimes see a black splotch in my vision for a second.  I've been told that's because the fast jerk is pulling the optic nerve on the back of my eye.  And the splotch is the back of the nerve on the retina(the "movie screen" part of your eye).\n\nWell, these are just examples.  But yea, go see a doctor.  I bet insurance would cover it and you won't lose anything.  Even if you've had this problem for years, it could get worse.  You never know.\n\n(Just if anyone was curious: I did have crossed eyes, but I had surgery to correct it cosmetically.  However, crossed eyes are not caused by the eye muscles being defective but by a lack of control of them.  It is more of a palsy because eye training can't completely "fix" the problem.  Cutting the muscle to weaken them does mask the "jerky" control, thereby giving cosmetically straight eyes.)

these particles are not really present in the light that you see. They are actually the nerves in your eye which are illuminated by the intensity of light. the same effects are not noticed when you look directly at a low intensity light(eg. Tubelight, zero watt bulb etc.)

I have some little dots in my eye, and my eyes change shades of colour depending on my mood.  Weird eh?  But like you the eye doc said I have excellent eyesight, mind you I knew that when I read the bottom line without squinting and he looked at me with his mouth agap.  I say don't fret it.

It sounds like floaters.  If it is, then you have nothing to worry about.  Usually you'll notice them if you are looking at a white board or the sky.  Some people have lots, some people have a few, and some people never notice them.\n\nIf you're interested, floaters are caused from protein clumps in the jelly ("vitreous" in fancy talk) on the inside of your eye.  As you move your eyes, they slosh around and cast a shadow on your retina, which is what you can see.  If you hold your eyes really still, you'll notice they slow down and eventually disappear.\n\nAnother thing that is a possibility are "ocular migraines."  I would recommend that you get your eyes checked by your family eye doctor just to be on the safe side.

My advice, take a guide.  Someone who has been through this before and can keep watch while you are on your vision quest.  Drink plenty of fluids, build a fire (a sweat lodge is good, but you need LOTS of water), and see what happens.  Good luck to you, don't try this on your own though.

Ditto.  My dreams are always vivid color with Smell-o-Vision, Texture-Vision, and even Sexual-o-Vision.  I am amazed at the clarity and realism.  I agree: The claim that most people dream in black-and-white must be a myth.

Could be "floaters".  Are you pretty short-sighted?  You'll see them more often then.  Good idea to go to your optician or doctor to get them checked out, though.

I have floaters. It has something to do with your retina. Should you start noticing many more just out of the blue, blurring vision, peripheral vision fading or blasts of bright light in your vision then you should get to a doctor quick b/c that could mean that your retina is detaching. Look it up in the search engine for more info.

Could be. You might also feel a tingling in your feet or on your body. If that happens, if your hair stands or you feel tingling outside, esp. when the conditions are right for lightning, HIT THE DIRT! That could make the difference btween living and dying.
