"Reversible Images" are also known as "ambiguous images", and they are optical illusion images which appear as a single display but can be interpreted as two different and distinct images.

An "impossible object" is also an optical illusion, which is a two-dimensional representation of an object which is immediately registered and interpreted by the brain as a projected three-dimensional object. These objects have a component which is registered by the brain as three-dimensionally impossible, and so they can be confusing.

Reversible images and impossible objects are illusions and not accurate perceptions. This is because illusions occur when the perceptual processes that normally help us correctly perceive the world are fooled by a particular situation, and so we see something that does not exist or that is incorrect. This is a result of our imperfect brain processing. Illusions demonstrate that our perception of the world around us may be influenced by our prior knowledge. Our emotions, mindsets, expectations, and the contexts in which our sensations occur all have a profound influence on perception.
