Is it normal to get: "you're different than anyone i've ever met"

I find I'm often told: "You're different than anyone I've ever met" by people I have just had a longish conversation with and with people I am close to. It's suppose to be positive, interesting, quasi-deep sort of thing most of the time (or all of the time I think?). Sometimes I have briefly thought to myself: "Well, I am *very* different from most people. It makes sense that people would notice this of me, as I have noticed it of myself." but then I think that is just the irrational human egocentric bias to think: "I'm *so* special". To me it seems the more likely explanation is just that a lot, most, or all people are told this from time to time and it's in virtue of the fact that people come in a wide variety and we also tend to notice differences etc. I myself have said that statement, or variation of it, to one person or more I'm sure. So, is it normal (common) to be told this? Please, share your stories.
