Pygmalion

 I was going to play the role of Henry Higgins in Pygmalion. I drove to the theater but realized I had left my costume (a suit) at home, so I dropped the actress playing Eliza Doolittle there and drove back. Then I realized that I had not memorized my lines either, so I never made it back because obviously I wouldn't be able to do it. Later, I was hearing some people  saying they had seen the play with an understudy doing the part, because the actor had flaked out.  I felt really bad about not having done the part, even though I knew at some level I was dreaming. I stayed asleep and within the dream had to take responsibility and hear the actress scold me for irresponsibility.  Obviously we had never rehearsed. Somehow I had assumed I could do the role just by the force of my voice and personality.
