Is it normal that i always feel like there's someone behind me?
Every time I'm in my house (it rarely happens in other places) I feel like someone's sneaking up behind me. Not someone I know or live with but someone or something else. If I try to resist the urge to look behind me, it literally gets to a point where I feel like I'll die if I don't look. I even see things behind me in the mirror that aren't actually there. If I'm walking in a hallway or through a room, sometimes I have to start running because the fear gets so intense and real that I feel like I'm being chased. When I was young (11 or 12) I used to have to walk down the stairs sideways with my back against the wall so I could see around me. Does anyone else experience this?
