Strange emails

I've been a bit concerned recently, as I have received a strange email. The only thing in it was this photo, which is a picture of a psychiatric hospital I worked at for a time...it has since been demolished, after a series of events which--well, which rocked the community, and are best left unsaid. I fear that one of my former patients is trying to reach me, and it has me looking over my shoulder a bit. Please pray for my safety.
