little hobgoblin spirit. Looks like he has some device to his mouth, another instrument type?

I see this hobgoblin as made up of tinier spirits. And yet again, there is something in the mouth. I'd think that yes, it is another musical instrument.

It makes me think also of the concept of crop circles being created through sound...which further reminds me of when I read Dr. Mitchell Gibson's book, Your Immortal Body of Light, learning that any power (to heal, levitate, etc.) can be had by knowing the right magical word/sound.

To which I recently had a dream that I made a certain sound and I began to levitate/fly. In my dream I was quite surprised I was making the sound. It was an unusual sound and I do not consciously know how to repeat it (make the correct tone, etc.), but in my dream I became lucid and realized what was happening, and that I was being given a demonstration of this word (sound) of power. Because I had asked to know.
