I find this happens with some ADHD people also, basically if you're dopamine seeking I can kind of get into this vibe. Often without knowing the person. It's just this... tug in my stomach toward someone. Like I can tell how their brain is misfiring because mine does the same thing. And talking to them is just like... I don't know. You just lock eyes and fall in. I ran into one of my 'trigger people,' yesterday, a friend I used to run around all night with and hook up with but it basically caused a lot of problems in our lives so we stopped (on neutral terms). Like, I haven't seen her in years and it was just all-lights-on-showtime. But even when we first met, I remember the same thing happening too. And I've had it happen again and again with people who have our same brain shit. WHY. WHY DO WE KNOW. HOW CAN MY BODY POSSIBLY KNOW.
