I like the dreams that don't repeat enough to be considered recurring, but that you've had before and can learn from. Last time I had this dream--the one where some friends and I are trying to sneak out the 4th floor window of our boarding school so that we could wiggle along the side of the building to a nearby balcony--I broke a window. Pretty sure another girl died. But this time, I remembered what had gone wrong before and managed to successfully remove the window without dropping it. However, reinstalling it was another issue.
