Wondrous item, common
While this journal is on your person, it magically records the contents of any dream you have. The dream is labeled with your name, date, and dream duration. The dream itself is recorded in long-form prose, as if it were a short story.
If you cast or are targeted by the dream spell while the journal is on your person, you can choose to transform the dream into one from the journal. To do so, the messenger and the target of the spell must both be willing, and either of them can end the dream (and spell) at any time.
It's a privilege to be given these moments, these fragments of your mind, and to see yourself revealed from within your sleeping soul.
Be sure to trust that version of yourself with only those worthy of it.
