I see demons, but they were created by my thought. The material realm constrains us, it makes us only see what was and not can be. If you see what there isn't, but would be, you'll open the sense of possibility. It's a skill that you'll continue mastering. Seeing more, in grater detail and consistency.
Why do I want to see demons? Because men of the earth worship them, dream to be like them. I want to see who they worship. Even if it's a crude imagination of their form.
