Albert's Spell of Relative Reality

There was a theory from a wizard genius that was "The theory of reality being relative proposes that the perception of reality is subjective and varies from person to person. It suggests that reality is not a fixed, concrete objective truth but rather a subjective experience shaped by individual perspectives, perceptions, and interpretations. This theory stems from the understanding that our sensory inputs, cognitive processes, cultural backgrounds, and personal experiences influence the way we understand and construct reality." this shows in this spell where you may make one illusion (any illusion!) into true reality
