*LOL at my sis's comment, about faery porn*
I think that your friend is projecting what she wants him to be, and that this other person is doing the same to her. They are finding what they want to see in each other and with that, is a deep intoxicating passionate love, the kind that takes you into the heart of fire and it has the potential to consume them both. I think the singer of connection IS the heart of the fire they will experience. Within this great love, this great passion the will make a solid connection with each other's spirits. Regardless of why they are meant to be so utterly connected, or if it will last, this connection isn't a mistake by any means. It speaks of karma, of spiritual height, of old wise souls that are meant to be "connected" even if it's only for a short amount of time.
The reason why I keep referencing a "short period of time" is that a love like this, so hot, so passionate, soooooo deep it usually will end before it both consumes both people completely. A fire that's out of control and will burn everything in it's path, consuming everything.
