Not a TAAT but inspired by one. What weird things have you said or heard someone else say in their sleep?
When I was younger I used to sleepwalk and sleeptalk a lot. Once I tried to evacuate my entire family from the house, claiming that there was a bomb.
My son seems to have inherited my quirky behaviour and unfortunately also gets night terrors. One time during an episode he shouted over and over again "Mummy's going to die!" which was lovely to hear...
