I love how people on 4chan speak out of their ass. Making shit up and trying to force it through as fact. You remind me of that guy from the show Cheers, who acted like he knew everything and spouted nonsense. Chopin had hallucinations of "terrifying creatures" that would emerge from his piano not being surrounded by the dead. Never, in any account, have they been refereed to as dead.
Now that image that you're saying is Chopin, has nothing to do with him. If you bothered to Google the image you would find the artist who made its page and see that piece is titled "Those who play for ghosts" And the boy depicted, is a grown up version of the boy that the artist uses in a continuing series of paintings http://themichaelmacrae.deviantart.com/art/The-Mothers-534672665?q=gallery%3ATheMichaelMacRae%2F9750975&qo=12
was his first appearance where he is being kidnapped by the creatures he is playing for in >>6510787
. There are 7 images in the series so far, and the last one is this.
TLDR. You're full of shit, stop lying and get an education
