Songs of Sadness

Bilbo fears he is losing his mind, He hears a song that drifts away then, the next day he hears it again but this time, he hears another verse, what scares him the most is that every time he hears the song and the words,their days seem to copy everything the song tells of. After a while he begins to wonder, maybe he does not hold the key to his some one else watching him?
