It started a few months ago but I started out seein people in the corner of my eye and when I look, nobody is there but it got wierd when I accually saw shadows of people in my room while looking straight at them. I also have a mans voice in my head. It's kinda a deep voice telling me what to do and criticizing people as I see them. It's a clear complex voice. I'm an 18 year old male by the way. But I also have been really paranoid lately too.
