You might feel low, kind of depressed, and there’s no clear reason in your own life for it. Just this heaviness that doesn’t belong to your circumstances. As if separation wasn’t hard enough, sometimes just their energy hits you like this too.
I think talking to your twin in your head is often a sign they are missing you because that’s their energy reaching out, and they do that because they’re missing you. It’s not just thinking about someone - more like you’re receiving their thoughts and responding to them. You might recognize your twin’s specific wording or their humor when this happens. That detail is what makes it feel less like imagination.
