it depends. personally my soulmate is another INFJ male, we have known each other and been best friends for eight years.
I don't know whether anyone has experienced this INFJ telepathy thing, to me it's really scary.
for example, I can tell from his eyes what he is thinking and feeling. it's like I can sense him in the air. when I dream of him, something happens to him on that day. it's really wicked weird(MA people talk in this way).
He can tell whether I am telling the truth solely from text message without knowing the truth!! for example, when I know something will hurt his feeling, I tell white lies and use some other thing as a cover. for most people, they just accept whatever I say, but for him, he knows me so well and he can predict which type of things can take my emotions to which level. He will ask me "are you really happy about this thing you told me? not other?".
it feels like I am totally transparent to him. Vice versa.
