This looks like the old Hendon Camp (I may be mistaken as they all look similar) up the slope. Been there just past midnite many years back with a group of friends. We has to park just at the road entrance before entering the yard that leads to this L-shaped building as there was a log blocking the entrance.
As we neared the right side of the building (partially hidden on the right of this picture), we heard dripping sound of water to what seemed like when it is raining coming from one of the rooms. It was a clear cloudless night. Then came a beast-like growl that came from that same room. The growling seemed more aggressive than a lion and it certainly gave us the shivers.
We turned around and left.
Till today, I remember very clearly that moment. Today, I think the authorities want to lease out the buildings around the old Hendon Camp.
I am not bullshitting and if any of you have ever experienced this, do share. If any of you were from the old Hendon Camp (1st Cdo), you know what I am talking about.
