I've read that in sleep, we are seeking to gain order and meaning from the random events of the day. That is what's clearly happening in these dreams that you've had.

I have thought that, indeed, my trousers might become too large if I lose anymore weight.)
That would be a good thing, wouldn't it, after the excesses of the holidays? I know it would be okay with me if I had to go down a size in trousers.

I miss the days when trousers used to go up to the waist.
