I don't really know a great deal about the Djinn but will say this, we as humans live on a strange "Y" intersection with one leg of the y representing spiritual reality, one representing physical reality, and the third leg representing the Astral which is the crossroads between the other two. And I am quite certain that part of our lessons here in this reality is to make sense out of things that have been foreign to our understanding for quite sometime. The Djinn as well as many other races are most likely a part of this same crossroad and are part of our lesson both positive and negative! These are my feelings only!
The Jinn are fabled muslim related creatures that come out of arab stories. I do not resonate with islamic things at all. I've read some of their book and honestly I just repel it all. I view the Djinn are Elementals corrupted by the Dark. Each one I meet, I free so to me its just another day at the grindstone. 2cents
