I love this. The graphic design is beautiful, and the concept of exploring dreams is really evocative and almost primitive in its nature, (by which I mean something that humans have been fascinated and haunted by for as long as humans have existed). I don’t really have an interest or experience with solo or journaling games, so I can’t really comment well there, but I do just absolutely feel the love put into this.
As for relation to the themes of the jam, it seems to steer clear of the more horrifying or troubling aspects of dreams, and so that makes it fit the theme well, I think.
