You should be able to perceive two different images.
This image is an example of an ambiguous illusion — a picture or object that requires perceptual switching between the alternative interpretations of figure and ground. And although you may be able to switch back and forth to see one image or the other, your eyes will not let you see both at the same time.
Our visual perception is created by our brain’s interpretation in the cerebral cortex of visual information entering through the visual pathway. And sometimes our minds get too involved in interpreting the perceptual input, rather than passively recording it, and make mistakes, otherwise known as “optical illusions”.
