Identify one example of Farquhar's distorted perceptions in "An Occurrence at Owl Creek Bridge".

In Part
Three of the short story, Peyton Fahrquhar images that he falls straight into the water
underneath the Owl Creek Bridge, quickly loosens his bonds, and rapidly swims to the surface of
the water. As Peyton is swimming away from the bridge, he dives and weaves through the water to
avoid being shot by the Union soldiers on the opposite ridge. Peyton avoids being shot and
successfully swims to the surface, where he crawls onto the dry land.

Peyton's distorted perception is revealed through his description of the
surrounding natural environment. Peyton immediately digs his fingers into the
sand, which he believes resemble "diamonds, rubies, emeralds" and is utterly
astonished by the beauty of the landscape....
