Cannot Rewind
Imagine yourself lying on a beach relaxing with your friends and suddenly one of them says: "Oh my God, I get so frustrated about that grasshopper singing in the background." and you answer: "What grasshop... Oh, that one!" And suddenly you can't ignore the singing.
You can never go back to when you were just sunbathing in harmony, you just continue to hear this grasshopper. It's the same with consciousness, you just have to learn to live with the "sound" even though you might not want to hear it all the time. It's there.
