Question about delusions and some personality disorders

Are delusions common in some personality disorders?

It's common in most of them, if not all. But it plays out differently.

Like the antisocial thinks he can get away with things, that life is a competition and there is no rule, so everything is permissible. That people can't hurt him, because he does not feel guilt and can endure pain. So strictly speaking, it's a type of delusion, or different belief.

I think it is central to narcissism. It's basically the delusion that your image is your self, what you project is truly who you are, and that you can control that image. People are there to mirror you as an example, and therefore they become an extension of yourself which can be exploited since you are also in control of the image.

So you could go on and on with all the others, I am sure they all have their specific delusion. Strictly speaking the societies we live in are also delusions, they are make believe things that don't necessarily mesh with reality. So they are delusions in that sense, but since it is a "normal" delusion, it is not called that. It might be called the "current thing" or the politically correct. or the faith, sometimes the customs. You need that to have a society, because the bondings are in themselves illusory, it's just habits, which can change, so in order to have "something", you have to create an illusion that it is. The only question is whether you can realize when it starts to be true, or stops being useful.

But in the sense of different belief than the normal, all personality disorders are delusional, pretty much by definition. It's a different belief of the self and social relationships. In and of itself it means nothing, it's more useful if you look in the detail of what difference? but it is not the type that makes it problematic, it's that it is strongly held and inflexible.

In a way but not the same way as with schizophrenia where you might believe that the fbi is poisoning your food because they believe you are onto their schemes etc. Identity issues and a realistic sense of self and who you are and where you fit into the world can be distorted. Thinking you are more or less than what you are. Also it’s in how you perceive things, disordered people tend to find the negative in almost every situation even when there is really nothing there. Perceiving slights and personal attacks that aren’t really meant that way taking constructive criticism that is meant to help as an attack on your character etc.
