It depends on the shape of the mirror. Sometimes, mirrors use something we like to call 'Optical Illusions.'

 
Optical Illusions can use color, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality, does not match the true image.

Hope that helps!
