Someone who beleives something to be true, when that something can be empirically proved to be nonexistent or otherwise incorrect. A snippet from an e-mail follows:

i recently lost my job and all my belonings do to being hospitail lised with the va .I HAVE HADE 7 BLIEDINGS IN THE PAS 3 -4 YEAR I WILL NEVER WORK AGAIN FOR MY LIVE i found this site very intresting and wood like very much try and find some covert in the study of ariail if you could help me be a member it wood mean so much to me your va patient patrick

Ilive in a travel trailer and have for 4 years sents my first bleed its been down heal from their my email thank you for your time it really goes faster thin you thank

This snippet is presented unedited, except for the e-mail address, which has been excised to protect privacy - and delusion. As you can plainly tell, the person here has suffered greatly from "BLIEDINGS" - which we think is synonymous with "bleedings" which would make this person delusional, as people (including stigmatics) do not spontaneously bleed. This person also thinks he can find comfort from his "BLIEDINGS" in studying aerial photos. You may notice that the phrase used is "find some covert", which indicates that this person may in fact be using aerial photos to conduct covert missions from the comfort of his VA hospital bed.

Whatever he's looking for, I certainly hope he finds it.
It is plainly obvious that "patrick" is delusional.
