Am I Locking Someone In

When you left I changed the locks on all the doors
And I swore I'd never let you in no more
But I feel your presence here just like a ghost
Each time I lock the door is when I feel it most
Am I locking someone out or someone in I've got a feeling you're in the house again
Oh I wish I knew what this was all about am I locking someone in or someone out
[ steel ]
I just watch TV till league goes off each night
Then I lock the door and turn out all the lights
That's when you walk here and I just stand and stare
I flip back all the locks and find there's no one there
Am I locking someone out...
Am I locking someone in or someone out
