What is up with this teacher?

Okay I’m a little freaked out by this teacher lately. He isn’t my teacher but the first time I noticed him is he’ll always be sitting in front of his classroom near my Cosmetology class and I always past him when I’m walking there. I sorta noticed him kinda staring at me but I decided to ignore it and that it could be nothing. Then one day he’s actually in the Cosmetology room and he’s sort of making lots of jokes and he also was asking the class who’s the loudest and who’s the quietest. Of course people point to me when he asks who’s the quietest since I’m very quiet and really shy and don’t talk much. He just replies with “I can tell by looking at you”. Then he asked me if I was smart like one of the smartest in the class. Then I remember him talking about hair? I’m not sure. I couldn’t hear exactly what he said but I think he said something about my hair. Then when he’s leaving the class he just points to me and he goes “You’re special”. I was the only person he said that to. I found it weird but decided he was probably just trying to be friendly. Now I always see him when I’m walking to Cosmetology and he’s always staring at me and I’m pretty sure he stares at all the other girls who walk by. He always comments on how quiet I am and he’s like “Are you like this in every class?” And I tell him pretty much and he just said he was curious. Then just recently for school I was having a day where I was more dressed up than usual. Just a shirt with a skirt and black tights and I walk by him, he’s staring again and he just goes “Look at you all dressed up today. Pretty”. Then the next day, he’s staring again. Finally I just go “You stare a lot” because it was the truth. And he just goes “I stare a lot? Nah I’m just spacing out”. I totally doubted that. Then he just goes “Do I make you nervous?” I sorta replied with kinda. Then he walks into the Cosmetology room and goes “I didn’t hear you. I said do I make you nervous?” I sorta just made a weird face and I’m thinking why the hell does he care so much? Then he just goes “I’ll take that as a yes”. Then he walks out. Now I’m not sure if I’m just exaggerating about him. It’s just weird how he is and the worst part is that he’s not attractive whatsoever which freaks me out even more. Anyone have any idea what could be going on here?
