Haunting connotations

This morning upon arriving at the hospital, I was reminded of the several times when exiting the building at the end of the day, my timing has been such that I have seen a Survival Flight helicopter landing on the adjacent landing pads, and have invariably found it eerie to realize that I first arrived at University Hospital by this very same portal, while comatose, on that long-ago day of May 22, 1993.
