All incarnations from your Higher Self are your soul mates. That means all type of constellations are possible male/female/alien etc. and all constellations can take place with the incarnations being in the same physical time and planet or not being in the same physical time and planet. Yes, your Higher Self consists of maybe 1000 to 10000 small soul fragments like you who is reading this right now. And all of those soul fragments are your soul mates/soul brothers/soul sisters.
Also, don’t confuse with Twin Flames, who are soul fragments/incarnations from other Higher Selves, but who are very similiar to you in personality.
