A hallucination is a perception experienced in the absence of an external stimulus.
Hallucinations come from “within,”although patients react to them as if they are external.
Pseudohallucinations are experiences that are similar to hallucinations but do not meet all the requirements of the definition of hallucinations
And does this say, anywhere, that it has to be indistinguishable from reality?
Again, what you are talking about is
delusions, which don't even REQUIRE hallucinations. Delusions are about beliefs. Hallucinations are simply about sensations.
If
feels "real", yes. It's external, yes. But it is perfectly possible to recognize that the extremely loud sounds of car crashes that seem to be coming from every corner of the room
and just won't stop are not real. They still feel 100% like external stimuli. But you can still
know they aren't real.
Seriously, you are like one of those fucking assholes that tell people they wouldn't be so depressed all the time if they could "just learn to appreciate the little things and cheer up a little". Or people who say I can't have depression because they occasionally see me smiling and laughing and otherwise enjoying myself. Would you argue that I have some sort of "pseudo-depression", because I can be well aware that I'm depressed? You have no understanding of what you are talking about, and quite frankly it is insulting.
And are you seriously trying to say, that a "hallucination" magically stops being exactly that as soon as you deduce it isn't real? That even though nothing has changed in the experience itself, the phenomena is different?
Because if this IS what you are saying, you're working off of what amount to essentially useless definitions that only serve to muddle relatively clear issues, so why bother trying to participate in a conversation at all? You're creating an arbitrary class of "things that exactly like hallucinations, except in this one way that's not mentioned in any literature and no one else feels is important but me". Next you'll be arguing that an illusion is only an illusion if you don't know it's happening or something crazy stupid like that, sheesh...
