I found out that the name of the novel isn’t actually Yumeutsutsu, but rather... it’s called Utsutsu no Yume Joukan (and there’s a sequel, with a slightly different last named, ended in Gekan), and they’re both prequels to Yumeutsutsu themselves... (there’s also a video nakedness Genmu, which it’s has two parts, 1 which is the basic one and is a video/colleague-thing that includes pictures from this, One way street-here again and once more, as well pictures of the canon mangas like Silent Sinner in Blue and Forbidden Scrollery; And the second part is Genmu-R, which is also divided in 2 parts too, one being a ballad song, which tells at the end the “epilogue” Of Yumeutsutsu, And then ends up into the second part which now includes guitar rifts and also a video too, which includes now images from... maybe the work itself? Or maybe is another work?, anyways, it’s also includes stuff like the epilogue of Gensokyo, which includes now all the new youkai, as well as Sumi too... (which makes me overthink a lot of stuff of this doujin and it’s relationship with Utsutsu Joukan/Gekan...)..
