The first sentence seems contradicted by the second no? If you don't have that fear then why bother playing around the semantics of "impression or notion"? Is it an unfounded or mistaken cluster of tokens which resemble an impression or notion then? At the end of the day it's producing an output which systemically was intended to be accurate, but ended up not being accurate through a mistake in generation: That's a hallucination.
