Hey people. You may not believe this but there is a condition called Alien Hand Syndrome. What the bejaysus is that, I hear you murmur. In a nutshell, Alien Hand Syndrome is like hands which have a seperate brain where the hands decide to do what they want, rather than what you want them to do. I know, it sounds kinda off the wall but I played a gig where my hands played different notes to a song I knew very well. It was terrifying. I was willing my fingers to play certain notes but Alien Hand Syndrome took over and my hand played random notes in a different timing and in a different key. I know you don’t believe me and this is why I leave you a url to the How Stuff Works site which explains it all. You can apologise for not believing me, later.
