Yeah, I’ve definitely experienced this. You’ll be doing something random and suddenly get hit with this intense wave of desire that feels different from your own energy. It’s like your body recognizes their specific energy signature.
Goosebumps and spiritual chills are my biggest tell. completely random moments, no temperature change, but suddenly my whole arm (and sometimes more of my body) is covered in goosebumps. The physical sensations can be pretty strong - warmth spreading through your body, tingling that starts in your chest and moves outward. And it comes with this need for them specifically. Nobody else, just them.
I think when one twin has sexual thoughts about the other, the energy does seem to transfer (I can’t really explain why, though). It’s like the connection transmits those feelings across distance. You find them attractive in ways that don’t even make logical sense sometimes. Not always just physical, even things I wouldn’t normally be attracted to in others, I really find myself drawn to in them.
When these waves hit, they’re pretty unmistakable. Your body just knows when they’re thinking about you that way. The pull is strong and very specific to that person.
