Why do hallucinations so often tell you to kill yourself? (In people with mental issues)

Right now there's at IAmA of the girl with Alice in Wonderland Syndrome. She mentioned that the hallucinations would try and get her to kill herself.


From other AMAs and TV/Movies I've seen that it's quite common for your hallucinations to try and get you to kill yourself.



Is there any reason for this? Is this actually something common, or is it rare?

There is probably an element of selection bias; a hallucination telling someone to hurt themselves or others has a better chance of manifesting  itself in a very dramatic way that's impossible for other people to ignore (suicide, shooting spree, etc) whereas a hallucination compelling you to eat cupcakes is going to have much more local (and harder to notice) effects.
