Things like that happen. Traumatic or life-changing events, major drug experiences, etc happen to someone and on the other side of it they're speaking a language they've never even heard or are tearing it up on a piano without ever touching one before. You're a lucky dude, but don't let it go to waste - practice and work on it and see how far you can take it.
seems lately i olny wanna play when im tripping , i have had some carpal tunnel problems and discomfort just leads to fuck it attitude.. but kinda convinced its more neurological than muscle related.. why the psychedelic drugs work idk..
reminds me of this individual that reported on the lsd/acid forum that after his trip, he could write and use his left arm like never before. i believe i gives u a chemical boost in areas of the brain that are never seen active. sweet stuff
