I love recurring dreams, particularly the ones that are not identical but are set in the same scenerio.
For instance, last night I had a dream in full techicolor where I'm walking around in a parking garage. I run into some others that are very frustrated because they can't figure out how to get out of the garage. I am able to lead them out because I've been here before but it's not just that my character in the dream "has been here." I literally have dreamed this parking garage and this city before but on a different topic.
