That might have been effects, because when I was isolated, there were people screaming on each side of the room and banging , but when I came out I asked, and none of them screamed or anything.Also the actors walk down the corridor banging on the doors, then they bang on the wall (which you hear very loudly from the queue and it makes everyone jump)In the corridor after the scientist (the one when the lights keep turning on and off and it gets filled with smoke) The actor told us firmly to keep strictly to the left, but they told the adult in my group to stand on the right (this was before the lights started going on and off) and I think they were going to take him down the other route, but after he refused to leave us they let him continue with our group.My first impression is that when the lights went off, they would take him away, and when the lights turn on our group would be 1 member less, I thought this was going to keep happening untill we were all alone, but that didn't happen thank god
