No Tags, possibly supernatural if you go that way

I feel you in these walls
You're a cold air creeping in
Chill me to my bones and skin
I heard you down the hall
But it's vacant when I'm looking in
Who let you in?

You walk around like you own the place
But you never say anything
I caught you walking straight through my walls
Guess it was all my fault
I think I let you in
