Is this normal that i hear and see things?
So everyday I hear weird noises and voices. I constantly hear someone slamming the door when nobody is there. I hear people talking, like they're behind me when I'm home alone. Yesterday I was watching a movie in my room and I heard pretty loud music coming from the living room and I thought it was just my dad listening to some music, but when I came out of my room everyone was asleep and my dad was silently watching TV. I asked him the other day if he was listening to music and he said he didn't. It also happened that I hear somebody turning the TV on and off, reading out loud or something similar. I don't know, maybe I'm just paranoid but could it be possible that someone is stalking me? Is it normal?
And sorry for bad English.
