Our nearest hospital is a big purpose-built 1970s building; well, it's getting like a little town now, what with all the improvements and additions.
Here is some weirdness I've heard from a reliable source.
1. In a certain hospital lift, an elderly woman sometimes appears after the door has closed. Source has seen her, possibly more than once.
Source took a friend to try out the lift in the hope that the ghost would appear to both of them, but the friend ruined it by screaming her head off in fear. Lightweight.
2. A man will walk in front of people along the Top Corridor, then disappear. Source has seen this too.
3. The operating theatres were closed down when new ones were built. Staff were happy because Theatre No. 3 was heavily haunted. Taps would turn on, light flick off and on etc and small equipment would be moved around, all when staff were present.
Plumbing and electrics would be inspected with no faults found.
After every day's work large equipment would be wheeled away from the walls by staff so the cleaners could access that part of the floors.
When the cleaners came on duty everything would be back where it was in the daytime.
Caused some friction between the cleaners and theatre staff as the cleaners would grumble about having to move it all themselves!
Source witnessed all this many times.
At some point there was a plan to hold a ghost vigil overnight but everyone chickened out. Probably too tired, being overworked NHS staff.
So as I was going to that very hospital the next morning after hearing all this I decided to ride the Haunted Lift. It's one I used when I worked there although the ghost business was new to me.
I called the lift, braced myself, stepped in and looked forward to a scare.
Sadly, it was Mrs Apparition's day off.
I'll certainly try again though.
