Yes you can be aware of your delusions. Example, I was watching the scary movie Carrie. She began to move objects. I was afraid I was going to gain that ability and because my faith teaches against such things I was scared. I knew I was not being rational and that I was not going to gain telekinesis. So what I did was instead of debating in my head and freaking out about if I could or couldnt gain telekinesis by watching that show. Is I just said I am not going to entertain this anymore and the fear faded and it is no longer a delusion of mine.
