This is one of the most common types of delusions, centering around a person’s fixed, false belief that others aim to obstruct, harm, or kill him/her.

See paranoid delusion for more information about this kind of delusion.

Example: A man believes he is the focus of a “vast, right-wing conspiracy” which results in his being spied upon and plotted against.
