Don’t really know if this is considered a superstition but I always thought of this theory that if you’re intently thinking about someone constantly like all day. Without the intent eventually it’ll cause you to pop up in their mind. Not sure how that would work but it seems possible. Or the opposite. What if you’re thinking about them because you’re on THEIR mind.
Seems probable imo but I’d like to hear from more experienced folks on what they think about this “theory”
