I dont get it, shes clearly turning cockwise due to the rotation of her foot, I dont get how anyone could see her as rotating anticlockwise??

ya and i have no idea if the brain thing is right

what she is clearly going counter clockwise

You can see it going either way. I tend to switch after every two blinks or when I bother bringing up the text for anti//clockwise.

it changes its rotation every so often. its a fake.

It's not fake or changing rotation, it's called an optical illusion geniuses. If you want to control it, keep your eye on one of her two arms; preferably the outstretched one. In your mind, follow it going in front of her and behind her. Then, switch it up (in your mind) and keep watching. Technically the silhouette in the image isn't turning more than 180 degrees at all.

I tryed it that way:
I leave my eyes on her standing foot and think, that she don't make a full 380 turn with it, but a little round movement. Now i can switch her dancingdirection like i want.

It is Fake. Its quite simple to tell. watch the shadow that the rotating foot Creates on the floor. You will notice that when the figure is rotating Clockwise her shadow appears when it should in accordance with the lighting. as in when the foot is closest to the viewer a shadow appears under it. however when she is going Counter Clockwise The shadow appears on the Ground when her Swinging foot is on the other side of her Leg furthest from the Viewer. I work with Graphic Design and Image Manipulation for a living so I can say with some certainty that I am right.
