I can feel how an audience is reacting when I'm on a stage, but when you are on stage, your perception is distorted. That's something you just have to know. It's like pilots that fly at high Gs and they lose, sometimes, consciousness and hand/eye coordination and they just have to know that that's going to happen. They have to be trained to not try to do too much while they are doing that. So when you are on stage, you have to be aware that you are wrong about how it feels a lot of times.
