We were locked into the Iso Ward, just the three of us. Literally a lockdown of the area if you will. We had been in this area for about an hour when a unknown voice was heard very loud and clear. We were all confused as we knew that nobody else was suppose to be in the Iso Ward.
I immediately went over to the starboard passageway and made my way back to the exit door where the guard had let us in and locked the door behind us. This was a good 40 feet or more away from us. The Iso Ward as with any small contained area would have sound reverberate and yet no foot steps or sound of somebody running down the passage way and no sound of the exit door being opened or closed. Yet nobody else was physically there to be seen.
Just my opinion here as there is no other explanation as there is no evidence anyone else was there, is this was a disembodied voice or AVP as Bob Davis likes to refer to them. AVP means Audible Voice Phenomena. Somebody once told me that Bob Davis was the person who coined this phrase.
We never heard from this unknown person again for the rest of the time in the Iso Ward.
