The "hallucinations " are seen by a father and son but no one else. Explain why the two of them see it. Also my brother confessed to me that hes been seeing preternatural things all his life. If they were caused by mere chemicals how come i never saw anything when i grew up right beside him. If you really want to be knowledgeable...be knowledgeable in all things. Automatically dismissing certain things and only accepting things that fall into the narrative you are most comfortable with is foolish. But i will say i do understand where you are coming from...altho i think the universe and all its...what you may call...facts...are beyond human comprehension.
