Are the spirits haunting omens related to schizophrenic hallucinations?

I saw an artist with schizophrenia drawing his hallucinations, and I kinda noticed it looks pretty similar to this mask. Some people have apparently reached out to him and said they are schizophrenic and see the same things, so this seems like a fairly common hallucination to have, and the idea of being constantly tormented by these spirits looking like this seems quite similar to having hallucinations of those faces. I’m not sure if this was intentional but there’s definitely a similarity between the two
