As if there isn't enough to be worried about in these days, some people are phobic to empty corridors, especially in hotels.
It's all the fault of The Shining, the horror film set in an empty hotel: ghosts (and worse) keep appearing at turns in the vacant corridors.
I suppose the horror is enhanced because what should be busy areas are disturbingly unpopulated.
In this deserted cinema, I even felt a frisson of something myself...
