Come to think of it, I had a dream once where I was pregnant and my thoughts about whether I wanted to keep the foetus were completely different to the ones I had when I was a) awake and b) not pregnant (or thinking I was). It's made me rather more reluctant to make plans for what will happen in the rest of my life, in case I'm really in that situation and my feelings about what I want to do are different to the ones I had when I made the plan, and also more keen to have a lot of money saved up.
