Never went inside but I drove past that place loads of times and there was something off about the upper floors, specifically the windows on the left side facing the old car park. My mate Darren actually got into the building about three months before demolition and he said he kept feeling watched in one of the stairwells and his torch kept cutting out. Classic stuff, could be explained away easily, but he's not someone who spooks easily so I took it seriously.
What's the shadow figure like - are we talking a full silhouette or more of a peripheral thing that disappears when you look directly at it? Because those are very different experiences in my view. The peripheral ones I'm actually more convinced by, paradoxically, because people tend to fabricate the dramatic full-on apparitions more.
Anyone got photos or know which floor this was on? Would love to compare notes before all the eyewitness accounts scatter now the building's gone.
