Sleep Talking

Robbie can go from being wide awake to fast asleep within seconds. It is rather disconcerting because he can fall asleep in mid conversation or even in the middle of doing something. Last night we were in bed talking and mid way through a sentence he started to talk about 'the Doncaster stop' I had no idea what it meant and he was not making sense so I couldn't ask him. A little later he was wide awake again, he seemed to be listening to what I was saying, but soddenly he shouted out '1955' then dozed off. I woke him and repeatedly asked what was special about 1955, he looked at me as if I was mad and in a very sleepy voice he said 'BR modernisation plan published, the dawn of the Deltics' - then he began to snore! If he is going to talk in his sleep I wish he could come up with next week's lottery numbers or at least something useful.
