I don't really understand what people mean when they say mysterious. This might have been a brain fart. So I looked the definition up.
Mysterious
Simultaneously arousing wonder and inquisitiveness, and eluding explanation or comprehension.
Hmm. With this in mind, I honestly find fellow INFPs to often be very mysterious. My best friend's boyfriend, for example... he is just hard to understand, but not necessarily in a good way. He's often frustratingly different from me. He says VERY little; I often just want to know why he never says anything. Does he have opinions but a fear of expressing them? Or is he usually spacing out? Or does he usually just not have an interest in the topics my best friend and I discuss?
In fact, on second thought, a lot of people are hard for me to understand, in a frustrating way. My mom, my ENFJ grade school friend...
So what did the OPer mean by "mysterious"? What does everyone else mean by mysterious? Is it a good thing? Bad thing? Neutral?

But strangely, I would not consider my friend "mysterious" in the way that I'm thinking. For me, "mysterious" is more of an aura of mystique surrounding someone/thing that is -- I know -- mostly a projection on my part. But I enjoy it as long as it's not harmful. It's like how people often perceive unicorns or mermaids -- or the Sphinx -- as mysterious. And I confess that most "people" whom I think of as "mysterious" in this way are actually fictional. Characters from books or films. Real life people are rarely mysterious to me in that way.
Ah. In this case, I have a hard time seeing anyone that way. Nobody comes to mind.
