I had a bit of a strange night last night. Not much sleep, and some bad dreams. One was particularly frightening.
I was in a crowded shopping centre, and gradually I became aware of a slow, repetitive siren alarm thing. Everyone else started to become aware, and there was all this murmuring of confusion, as people didn't know what they were supposed to do.
It was then announced over a loud speaker that a man with a gun had just arrived at the airport, and was making his way on foot to the shopping centre. Everyone was told to hide. In dream logic, there was no way to get away, and this approaching figure made everyone absolutely paralysed with fear. There was just this absolutely dreadful inevitability to it.
I woke up just as the man entered the shopping centre, which was a relief, but I still now, hours later, have this uneasy feeling because of it.
