That's a neat dream. And LOL about Johnny Cash! That's wild. You + he have something in common!
The closest I can come is the other night I dreamed about Dick Cheney. He was standing in a suit somewhere talking and talking, and I came up to him and tried to squeeze his balls. He kept going on and on about the Iraq war and Guantanamo being great ideas, so I kept twisting and squeezing his ballsack. But he seemed impervious and kept on talking.
