A similar thing happens to me sometimes. Something will happen in a dream that I don't like, and I'll be like "Eeeh, I don't really like the way that happened." And I'll rewind and do it again. Sometimes I'll re-do a certain part of a dream 3 or 4 times before I'm happy with it.

There was one time where I re-did a whole dream. I was a jewelry thief, for some reason, and kept getting caught. It was a variation on the dream where you are being chased, but I was always re-do, or try different ways of escaping when it looked like I was going to be caught. Eventually I got really frustrated and started the whole thing over from the beginning. Never did get away, though.

This usually happens after I've woken up in the middle of a dream, usually quite late in the morning, but don't want a dream to end, so I just go back to sleep and hop right into it again. That's when I really get the most control over them. I only just really got into lucid dreaming a couple days ago, so this is all before every really knowing about it. I thought it was funny learning about WILD, because that's basically what I would do without thinking about it. I always somewhere in the back of my head knew that it was a dream, (especially since it's the same dream I just woke up from, so I've already identified it as a dream) but never really made it a conscious thought. Now that I know to watch out for that, maybe I can make these semi-lucid dreams completely lucid. I'll have to wait for some time when this happens on a morning I don't have somewhere to be and can go back to sleep.
