Is this normal ?

Is this normal? So I’m 23 years old. I work with a man my manager. He’s like 40 something years old.I’m not attracted to him or like him in a sexual way But it’s odd. Whenever he comes close to me I get this feeling like my body wants him to come closer to me? I know this is strange because he actually hates me. He treats me mean almost every encounter, he’s tried to get me fired, he Doesn’t even like me.
