Man permanently thinks he is a glass of orange juice (or becomes an orange)

Another common legend, again dating back to the 1960s, was that a man who took LSD went insane and permanently thought that he was a glass of orange juice. Because of this, he could never bend over, slept upright and did not make any sudden movements. Alternative versions sometimes have the man thinking he is a glass of milk or a whole orange. Another version of this myth states that the man believed he had become an orange, and was afraid he would be 'peeled' by his friends. This particular tale is now considered to be unfounded.
