My father has full delusional disorder. No doubt. I'm 36 and I am starting to realize that I have a milder form of it. Erotomania, messages from tv/radio, thinking people can read my thoughts etc, although it's getting better the more insight and awareness I get about it (through traumatic social experiences).
When I was a child, whenever my arms or legs fell asleep, I thought other people could feel the tingling sensation that I did. I remember my Mom touching my arm and saying, "No, I don't feel the tingling like you do". Does this sound like an early indication of delusional disorder?
Also, I hate to admit it, but in 1st-4th grade I plagerized alot. I would find a poem that I liked from a book, write it out on some paper and put my name on it as an assignment (write a poem or story). I really believed that I wrote it and I got alot of admiration from teachers about my "writing abilities". I have not done this since the 4th grade.
