Referring to one's self in the third person

Now it might be that people who say their first name a lot are pretentious and grandiose — you know, full of themselves. On the other hand, saying "I" can be more intimate, so if Bob were to find intimacy challenging, "Bob" could be a wee bit easier on the brain. "Bob really likes you and hopes you don't find his way of speaking too wacky." Could Bob be uncomfortable in his own skin — so much so that he's talking about himself as if he were someone else? And although it's extremely rare, such talk could occur in people with psychological disorders and illnesses that have speech abnormalities and changes in personality as consistent and long-term symptoms.
