Ever keep a dream diary?
It's easy to do.
Just keep a journal or pad of paper and a pen near your bed.
Jot down any dream fragments you remember upon awakening. If you're able to write them down before you are fully awake, you're likely to remember more.
Re-read some of those entries in a quiet moment. You just might have some interesting material for a short story, drawing, or other form of art.
And then read this BryonySeries novel. The main character winds up time traveling to the nineteenth century in her dreams.
Or does she?
