Intuition?

I'm a 30 year old female who has always felt like I had some sort of weird intuition about certain things and circumstances. I've just always has a weird sense for bad situations and premonitions about things. Lately I've been seeing shadows or images out of the corner of my eye, yet when I do a double take I see nothing there. This mostly happens when I'm at home alone or when it just me and my young daughter. At first I just brushed it off, but it has been occurring much more frequently lately and I'm starting to get a little freaked out. I live in a extremely old house (circa 1900) and its to the point where I don't want to be there alone. Yesterday I was walking past my closet and the door was open and I swear I thought I saw a person crouched down underneath some hanging clothes. I stopped, turned around and walked back to the closet to take a closer look, but it was nothing.

I also have a strange obsession with the show Disappeared on the ID channel and when I watch certain episodes I get extreme chills, goosebumps and my eyes water. It has only happened with 2 missing persons cases I've watched, but it was an very odd feeling and sensation. Now I've become rather intrigued by one of the cases, but it's hard for me to read about it because my eyes water so bad and that weird feeling comes back. I haven't mentioned this to anyone else, but it also freaks me out. I know this probably sounds crazy, but I'm wondering if this could be that intuition I've always felt or could it be nothing?
