This is one of those things that I'd never confess in RL because it makes me sound like I'm 7 but I often wonder if other people feel the same.
Now, I'm an atheist, I don't believe in ghosts or ghoulies or anything like that. Never had a supernatural experience, never 'seen' anything.
But. I live alone (for now) and sometimes... I just have to look behind me to check. Sometimes I just have to go downstairs one more time to look round the living room before I go to bed. Sometimes I freeze when I'm brushing my teeth upstairs and wonder, is that something coming up the stairs?
It's not burglars I'm worried about. It doesn't even have a definite form. It's just something that might be in the mirror, or right behind the just-open bedroom door.
AIBU or do you get that too?
