Distortions happen in a photograph when the look of a subject become skewed due to angles or proximity between camera and subject (too close, too high or low).  Reflections in a photograph become interesting when the two-dimensional reflection becomes the focus rather than the three-dimensional subject itself (any reflective objects can create this effect, water, mirrors, shiny cars, doorknobs…).  Make sure you shoot at enough of an angle that you are not part of the photograph (unless that is your intent).  See examples below.
