Well idk why this happens, but it does and i LOVE IT. Im playing "Time of your life - Green Day" on guitar and singing it. While doing so, i close my eyes and imagine im playing in front of thousands of people. Next thing i know, my guitar gets quieter and i start hearing voices. Still having my eyes shut, i finish the 2nd chorus and go on to the third and find out that im hearing a big crowd of people singing along. Akward, scary, and entertaining to me. I love the fact that i can imagine that and start hearing crap. Gimmie ur inputs please!
