Well, for starters, some people won’t use the term “pull” to describe it because it’s more of a heart pain. Some do talk about an actual physical pull that they have to fight towards and others are going to use that term in a much more… general sense. I have no doubt there are people with karmics or even just 3D relationships that would describe some kind of “pull” that is just 3D-driven.
A lot of these experiences are going to be pretty unique and varied, so I don’t know if you’re going to get a checklist. You might want to take a look at the conversation on figuring out if they are your twin flame.
You might experience an actual energy field around you. Like the space around your person is different from anyone else. You can tell if it’s them standing behind you or if it’s someone else.
Some have heart palpitations that feel electric, tingling or goosebumps all over their body, dizzy spells when near them, chest pain or what feels like their heart expanding. Some describe it like being on mild psychedelics when they’re together - chakras lighting up, feeling high from the energy alone. The intensity can be so strong that some people have to rule out actual heart problems.
Then you have runners (most often) who are able to discount this kind of physical response as “probably nothing”.
There’s no checklist you can use, I’m afraid.
