The Right Brain vs Left Brain test ... do you see the dancer turning clockwise or anti-clockwise?
If clockwise, then you use more of the right side of the brain and vice versa.
Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.

If you can't see her rotating in the opposite direction, look at just the foot shadow and try to see it as a bird, with a large beak, bouncing up and down and moving its head from side to side, not spinning it's head around. You may have to cover up the turning girl by putting a book or something on your screen so it doesn't distract you. Once you can see that, you will see that depending on which direction your mind catches the birds' head turning, to the left, or to the right, determines the direction your will see the girl spinning.
Basically what's happening is you're really just looking at a set of 2 dimensional images. Because of conditioning, you see a 3D object of a girl spinning around. If you were to take a real 3-D model of this girl and take a series of photos of her spinning in one direction, then took another series, timed exactly the same, and the same number of photos, of her spinning in the other direction, then placed the sets side by side on a table, they would look identical. You would not be able to tell which way the model was spinning when the images were taken.
So all you're seeing is a set of "flat" images that would look exactly the same no matter which direction they were "perceived" as spinning. The amazing thing about your mind is it can see multiple realities at the same time. The key in this example is your mind sees the shape that looks like a shadow of a foot spinning, and it also sees the same shape as a bird looking from side to side.
Because we "know" this is a picture of a girl spinning around, your mind simply picks up the direction you notice first from the shadow foot, and fills in the rest. Once you can see the birds' head moving from side to side you'll see you can switch rotations by simply looking up at the girl as the birds' head turns left . . . she'll spin left. When the birds' head turns right, look up and she's suddenly spinning to the right. You'll see you can switch back and forth at will.
So I guess the big lessons here are we all have some basic inclinations that determine the dominant way we perceive the world around us. But we are not limited to perceiving the world the way we are inclined to automatically perceive it. We are all capable of seeing the same reality in radically different ways if we simply choose to look for it. We are wired with much more flexibility than we are conditioned to believe. It all comes down to what we want to see. And you can now see that it's totally possible for two completely opposite realities to exist at the exact same time. So hopefully now you will be a little more willing to consider that other people can actually have opposite points of view that are equally as valid as yours, even though you can't really see it. And hopefully you'll be a little more willing to try and see the reality of opposing points of view before you discount them entirely.
