I think this song is about being in denial about loving someone.

All the things he says like: "I can feel you watching even when you're nowhere to be seen I can feel you touching even when you're far away from me Every time I see you, I don't know why my heart begins to race Every time I leave, I don't know why my heart begins to break" those are all symptoms of being in love.

And this is so new to the person, that they think it some sort of spell because it is such a strong feeling.
