A Rehearsal Dream involves a run-through of an actual planned event you're expecting in the near future. This type of dream allows the subconscious to prepare in advance for an important or potentially traumatic event. Depending on your emotions about the event, your subconscious may choose to run through either the best-case scenario and the pleasure you expect the event to bring, or the worst-case scenario and the potential disasters that you're afraid could happen. In the worst-case scenario, because the dream tells you what your fears are, you have a chance to work through them before the event, if you choose to.
