Uneccessary specifics of dreams

Last night I had my usual round of peculiar night time experiences, but this time with an odd emphasis on the specific: At one point the Boy Wonder took some salad out of the fridge to eat, and I was a bit worried that it had been in there so long that it would have gone bad, but I didn't want to say so in case I gave the impression that I thought he was incapable of working that out for himself. A colleague of mine asked how fast a person could walk a mile - I answered that average walking speed was 4mph, but then said a mile should take 20 minutes to walk. As I sat there, I wanted to correct myself to say 'of course, at 4 mph a mile should take 15 minutes, but I meant that he should allow 20 minutes to be sure' and when the moment passed, I was really annoyed with myself for not speaking up. I sometimes wonder whether my night brain is trying to make me the sort of person who pays attention to detail that I sometimes want to be whilst I am awake. But if this is all it can offer, then it can bog off as I already have the ability to worry about tiny details that I am pretty sure (objectively) nobody else would even notice - it's other details (remembering dates, tasks and information) that I need to brush up on. I also seem to remember something about sharing the details of your dreams and how fascinating it can be for others...
