Have you ever met someone that gives you the shivers ?

I see this guy around in college everywhere I go it's kinda creepy but scary at the same time.

He stares quiet allot but his eyes and face have no expression and emotionsat all don't think I have seen him smile once. Which gives me a unsettling feeling whenever I see him makes me feel like I am at danger when I know I am not.

Has anyone got a bad feeling of vibe meeting someone completely new. Like feeling a bad energy around them.
