When thinking about the idea of different realities, I am reminded of the fallibility of witnesses. Many studies have been done that test the accuracy of witnesses, and the results are somewhat alarming. For instance one study showed that when a gun is introduced, people's accuracy in describing anything that happened in the situation goes down, to the point where they can remember incorrect facts. Witnesses also often identify innocent people as guilty, and remember situations in different orders. While it is incredibly unsettling to imagine that our reality is not in fact the reality, it is not surprising that our senses can lie to us, given this information. It also suggests that vision is not the only sense that "lies", and that even with all the senses together we still get a highly biased and personal reality.
