I do think, at some deep level, we all have a desire to be "special"...there is nothing wrong with that and, hopefully, in our lives we are special to a few, just as some people are special to us.
The problem comes when you begin to believe that you are Unique in your pain (or, I suppose in your Rightness/Perfection) And, now that I recall, the phrase I used to use was "Terminal Uniqueness"...because, unless we realize that we all have things in common with others, we miss out on the great beauty and true pain that can result in growth...
You end up, in this crazy "unique me, nobody can understand me..." isolating yourself in a sad, small, painful world of unreality.
