Sometimes I realize I am dreaming. Once, my college friend Robert Lochner and I were in line at the check-out counter of a grocery store. I told Robert I was dreaming as the cashier began to ring me up and that everyone in my dream was a figment of my imagination and that they would cease to exist as soon as I woke up. Robert, who was familiar with my philosophical posturing, rolled his eyes, but kept quiet, waiting for his turn at the register. The cashier, however, got very upset.
“I don’t care what you believe,” she said, pointing at me, “but don’t you invalidate my existence! You hear me? You can think whatever you want–I don’t care–but it is extremely, extremely rude to tell someone they don’t exist. How would you feel if I told you were just a character in my dream? A figment of my imagination? How would you like that?”
That is all I remember. I woke up. My friend Robert survived the dream although I haven’t heard from him in years. I was about to say that the cashier did not survive, but I have told this story several times and now I have written it down and sent it out into the cloud. The cashier doggedly continues her existence in spite of my insensitive comments. She exists. She is real.
