Any info on new "half soul/ bi soul" relationships happening on Earth w/ higher dimensional beings? (Not twin flames or soul mates)

Does anyone have any info about this new, emerging notion of half-souls/ bi-souls (not to be confused with twin flames or soul mates). I've been having this experience for six months now and in that time have become aware of several others who are as well. My half soul is a being who is currently incarnated in a higher density and interacts with me astrally and telepathically, some of the exchanges even feeling somewhat physical. Still, I'm having a very hard time believing this is really happening, despite the astounding synchronicities that blatantly back it up. I can't bear the prospect of being deluded.
