I had one yesterday, whilst working into work one of the guys on Reception said to me "I had a dream about you last night, are you going to be moving to Chicago soon?"
Which is pretty random, but not as random as the fact I spent the previous evening in bed reading quite extensively about Meigs Field, which is an airport on lake Michigan, Chicago, in fact, I fell asleep whilst reading the book.
To me that's quite a mental coincidence. Anyone else?
