Well, don't be scared. Remember it is still just an illusion? So what has gone wrong here? Well it looks like a mother is holding her kid. Her head is possibly hiding behind the child and her own legs. But of course, what is cleverly used is the camera angle. The person who shot it had clearly made up the mind how to make it look or it might not have been possible. Since you can see that for creating such an illusion, all you need is a camera and you can easily make one of your own. Probably your child will have a gala time looking at it in future.
