Am I Some Weird Psychic?

I'm a little confused. Am I some weird form of psychic, seeing ghosts or am I just going insane?

So there's a few things going on, but they all kind of fit together.

The first is I'm seeing things that no one else does. Such as people and shadows that aren't there. Here's the confusing part though, I know that no one else can see it because I can see that they aren't really there. I can see these things but not with my eyes. It's like pictures or a little scene playing on repeat in my mind. But sometimes those things stop and look at me; And when they do, they kind of sway, but it's more twitchy than when you or I would sway side to side. The only time I can see these little scenes is when I'm looking through a door way or when I'm at a very specific spot. Like the second from last step on the stairs at my house. I just get this feeling of severe isolation and fear and above all, the feeling that I'm not really there, like I'm somewhere else, and the things starting flooding my mind with the images and emotions that aren't mine. It just gets so overwhelming that I start getting dizzy and then when the dizziness passes I'm just numb. I can't feel anything and the pictures are gone. All that's left is a feeling that I NEED to be away from there.

That's the second thing, the dizzy-numbness and the need to be away from there. There are certain places that I get to or certain things that I touch that make the overwhelming feelings and fear and dizzy ness come back. Only some places are worse than others. Such as the door knob to my little sister's room. I'll start to turn it and as soon as the door opens, It hits me like a big unwanted wave of emotions. But no pictures or scenes when I touch objects, just emotions and dizziness.

And the third thing, I'm not sure if it's just me or if other people get this type of feeling too. I get like these feelings or vibes, whatever you want to call them, from certain people. I don't know what it is about them but they just make me so aggravated and frustrated and I get such terrible headaches around them. Even when they haven't done anything and even if I don't know them. It doesn't matter what my mood is. And it's horrible in a crowd. Almost like the dizzy feeling from those things at my house, but in headache-form. It's not just that people are influencing my emotions, it's like they're just being replaced. No transition what-so-ever. Like I'm going straight from overly happy to depression or anger. But those weird mood swings don't happen when I'm alone.

So my question remains, IS there something wrong with me? Or am I just some odd form of a psychic?
