Church full of people

This is a reoccuring dream that I have, although it's not always quite the same. Every so often I dream that our church is full of people. Last night I dreamed that I was trying to play "Shout To the Lord" but I was really struggling with it. Some of the chords were chords that I had never heard of before, like P and Q. I finally gave up trying to play it. My voice was really weak, too, because since Donna and Danny left our church, I have to sing by myself and I was having a hard time singing loud enough to be heard. But as I started to sing I realized I wasn't singing by myself--I could hear other people singing with me. I looked up and realized there were people standing and worshiping God and singing, and more people were coming in. The whole church was praising God like never before, and it was packed full of people and no one even noticed that I couldn't sing or play.
