The grammar in this article was recently changed from "a hallucination" to "an hallucination". However, whether it is "a" or "an" depends on dialect - here in Australia, it is definitely "a hallucination", and "a hallucination" is the more common way to write it worldwide. Now, since this wiki is in British English, if someone can find proof that British dialects use "an hallucination", then it should stay that way. Otherwise, I think we should use the more common way of writing it. 1.129.108.252talk to me 23:51, May 6, 2019 (UTC)
