Is it normal that i think differently than everyone else?

So I almost never feel any kind of emotion. When I do it is always either attraction (not necessarily romantic, just that person is really cool), sadism (wanting people hurt and in tears begging for mercy, which I refuse), narcissim (being overly concerned of how people think about my brains and how theirs are too small to understand what I understand (sometimes I solve mystery books parway through, which doesn't work well with my humbleness)), anger (but even then I am usually still pretty level headed and think through what I'm doing), or sadness(never anything specific, just anything and everything). I never feel amusement, embarassment, or any other emotion listed above. When people get hurt (real life and movies), I feel the urge to laugh. I'm a good actor because I always have to figure out which emotion a normal person would have and act it out on the spot, without warning. My entire life feels like a lie. When I open a present, I'm not disappointed, but I never feel surprised or happy, even if it's something I really want/didn't epect. Sometimes I hallucinate. Part of the time it's just noises (screams, people calling my name, or footsteps), part of the time it's things that aren't there (i.e. Slender Man, little blue and white stuffed animal watching me), and part of the time it's seeing things wrong (like thinking a laundry basket is a small child, mistaking a clear glass bowl for a metal one that screws into something). Everything feels so disconnected, almost like I have two minds in one body: one for thinking and one for doing (sometimes I do stuff without intending to do it, although it always eems to be thought through beecause there is almot never bad consequences). It's almost like when you're playing a video game, your mind for thinking, and your hands for playing. It's maing me really nervous because I've never heard odf anything like this, I don't know what to do. Should I see a psychiatrist? I just really am not sure, please help, I'm scared.
