The story behind it is as follows:
This picture was taken using my iphone 4s camera, in one of the corner cell blocks and i was ALONE in that cell room, as well as the surrounding area. This cell room contained all the original instruments that was used to perform executions by hanging such as ropes, face covers etc, and was contained in a chest. Right beside the chest was just a mannequin to display how a prisoner would appear on execution day such as the clothes they would wear. The mannequin and the chest were protected by a floor to ceiling glass as these items are authentic and in its original condition. This room was just located across from the scaffolding of where the execution actually took place.
If you have a look to the right of the photo you can see my reflection. As i mentioned, i was alone in that room as well as the surrounding area. Right behind on top of my head to the right, it appears as if someone was standing behind me, but as i said i was alone, and if i knew that there was someone there then i would have shifted aside for others to be able to peer in or come into the room as i did not want to appear as if i was hogging the tight entrance. I would've been able to hear if someone was approaching nearby. Ive also tried to look in between my feet in the photo to see if there were any legs belonging to that head-like figure behind me but i cannot see any. Perhaps you may have other resources to better and analyse the photo than what my eyes can see. I did not feel any shifts in temperatures but i did feel extremely nauseous and sadness for the entire duration i was on the second and third level of cell blocks. My partner too had also felt nauseous but that was all that he felt.
