I can't really say anything because i'm not a neurological person but intresting story. Mine are nothing like yours, i have never had a "haunting" or anything. I once saw a white figure of a man come down the stairs in the darkness turn to me, smile, and walk into the darkness and dissapear, but i was a kid looking into the dark, we see what we wanna see in the dark. The more i rationalize my stories, the more i see they are just that, stories. Just because i can't explain something, does not mean it's the supernatural. The mind is a powerfull tool and it can literally ruin your life with paranoia and stuff.
