This work of yours, for example, reminds me of the ghosts that haunt psychiatric hospitals. I wouldn't dare say whether they are involuntarily produced by the psychiatric patient, or if they are external entities that feed on the patients' energy... It could be both... They move objects despite being invisible. They bang on walls. Things are heard even when no one is in the room. Some of these entities become so powerful that they take on visible forms, or break things.
If you witness it, you might think it was a hallucination, or that you saw it in a dream. But this is based on cases witnessed by everyone: visitors, doctors, and patients. It's one of my favorite taboo subjects.
