Went up there on Saturday actually, around dusk. The whole eastern wing near the old treatment rooms felt completely off, like the air was heavier or something, hard to describe properly. My mate who came with me kept saying she had a pressure feeling behind her eyes which she never normally gets.
What I found strange was my mobile kept losing signal in one specific spot even though I had full bars everywhere else on the grounds. Kept happening in the same place every time I walked back through it.
Did anyone else go near the lower basement entrance? There's a bricked up doorway down there and I genuinely couldn't make myself stand in front of it for more than a few seconds. Not scared as such, just an overwhelming urge to move away. My torch also flickered twice in quick succession right at that point which I know sounds like a battery thing but it was a brand new set of batteries.
Would be really interested to hear if others picked up on anything similar or if we're all just spooking ourselves out.
