When you’re communicating with their higher self, you usually feel that pure unconditional love, the oneness. It feels like peace, like truth. Their 5D self knows nothing except their love for you. But relating to them in 3D can feel completely different, sometimes (read: always) upsetting or confusing. Both are just as real and just as important. Different aspects of the whole union.
The physical 3D self of your twin isn’t as wise as their soul because we forget everything when we take a new birth. So their 3D self might make mistakes, might not have all the answers, while the soul sees everything from a higher perspective.
Sometimes you might feel your twin thinking about you, and also receive loving messages from them. One could be coming from their conscious mind, while the other is from their soul/higher self, which remains in love with you at all times. So that can get… confusing. The messages feel different but it takes time to feel that difference to see where it is coming from.
The more both twins awaken and grow spiritually, the more you naturally align with higher selves and divine will. Then eventually the 3D catches up.
