I have had several dreams involving being in a show preparing for opening night, and not knowing several songs or most of the blocking...
I also dreamt that I forgot that I had tickets to Cry Baby on Broadway (when I actually did, two weeks after it closed, in real life), and missed the show. I was pissed in my dream.
Also, not too long ago, I dreamt that I got to the Imperial Theatre to see Billy Elliot about 10 minutes late, while Shine was hapenning. Now, the theatre was built much like the Circle in the Square, but with two levels, if anyone knows what I mean, though that's obviously not how the theatre is actually built. I was on the right side, and down the row from me was Jimmy Fallon. At intermission, he offered me a job on his new talk show. Then, at intermission, I left for some reason and was again late for the 2nd act. I was angry that I had missed so much of Billy Elliot. Then, I woke up and realized that I would be able to see the whole thing in real life, and was very happy, haha.
