You have an exceptionally good wordchoice and imagery going on in the first three stanzas. The image of the silhouette streaming almost ghost-like into the darker corners of the soul. Your term "syndromes of the night" is also well thought out and so apt of a discription. It's strange to say that you take us on a pleasant descent into dark emotion, but it's true. You allow the reader to slowly sink into it rather than jerking them down. Overall this is a very nicely done piece. You've given eloquent discriptions to such raw emotion.
