<P> The Mystery Spot is a gravity hill , tilt - induced visual illusion . The illusion experienced by visitors results from the oddly tilted environment as well as standing on a tilted floor . Inside the tilted room of the Mystery Spot , misperceptions of the height and orientation of objects occur . Even when people are standing outside on a level ground , the slant of the building in the background causes misperceptions as humans judge the height of people using the slant of the roof rather than the true horizon . </P>
