Classification is difficult because strictly speaking there is no unified classification of these texts. If I had to give it a description, I think they are just real notes about ghosts. It just records some incredible experiences that I and my friends living around us have experienced. Scary things, sad things, tender things, sad things, it's all in there. Please don't ask me what to do if I encounter them, because we can't answer this, we can only encounter them and walk with them...
