Is it normal to have a crush on someone you don't know?
Yep.Totally normal
Yes, it’s completely normal to have a crush on someone you don’t know. Sometimes a look, a vibe, or a brief interaction is enough for your imagination to take off.
A crush doesn’t require knowing someone well. You might be drawn to their appearance, the way they carry themselves, or a tiny moment you shared—and your brain can fill in the rest with a little fantasy casting.
Lots of people develop crushes on strangers or near-strangers. It’s usually harmless; just remember that the real person may be quite different from the version your imagination has dreamed up.
