actually in some people OCD can cause a person to have psychosis, hallucinations and delusional thoughts...

example...me.

when I am home alone one of my compulsions is constantly pacing from room to room. I have a ritual i do in every room in order for me to feel safe. it is a repetitive motion with my hands, where I am constantly flexing and fisting my hands as I enter each room. I also have the compulsion of listening at doors and windows when I am alone, making sure no one is on the other side, making sure the doors and windows are locked. then even though I already know all the windows and doors are locked I pace around from room to room again. sometime I get so fixated on this compulsion that I begin to hear voices that are not there, start seeing peopled shadows that are not really there (my treatment providers call this OCD induced psychosis and OCD induced hallucinations) Sometimes it gets beyond this to where my thoughts are on the delusional side.....someones out there, he's going to get me, whats that, got to find something to protect my self, I know Ill turn into being like the eagle and fly away from here I can do that I bet if I tried...my treatment providers call this OCD induced delusions.

OCD affects people in many different ways just because you dont have the symptoms of hallucinations/psychosis and delusions during your OCD problems does not mean every person with OCD is like you.

hallucinations/delusions and psychosis can happen to anyone regardless of which mental disorder or physical problem has. and they can happen as part of any mental disorder or physical problem...

if you type in a search bar .....OCD plus hallucinations ......you will find there are millions of people out there that have OCD where it presents itself with hallucinations. the same with delusions and psychosis.
