Logic in dreams
I have tried to do maths in dreams before and found it very difficult. But just now I had a dream in which Ange had invited us all to a late movie (3am! that's crazy Ange, what were you thinking!), and during this movie we were all talking about stuff that was going on in it. Anyway, there were 191 space cadets left after a mission and they were in groups of 13, so we wondered how many had died. Ange said that seven 13's were 91, and I said that meant there must be 14 13's in 191, and 13 squared is 169, so therefore 14 13's are 182 so the remainder is 9 (I could have just doubled 91 though). Then I suddenly realised (while still in the dream) that we shouldn't be able to work that kind of thing out in a dream, and Sven said I should put it in the wiki - so I woke up and here it is - now I'm going back to bed :-)
