This is an image that I created that was based on one of my ideas of the incorporeal beings coming in contact with a diary of a perhaps long dead.
The diary would have a sort of a part of the owner because they poured their emotions into and therefore the incorporeal beings can sense that and interact with this essence.
Also this illustrates my idea that these beings would emit an aura of light, but what I really wanted was to have light emitting but the source would not be visible.
Also the “skull” shape might be noticeable and that just represents the fear of other humans who see this event happening. No one would see the books essence until the incorporeal being got close sort of like a flash light in the dark.
