I looked at your post the first time but obviously didn’t absorb it. Have you ever been introduced to something, zoned it out, and then found a reference somewhere else and think you discovered something?
I was reading a book that Megan told us about (River Magic by M.A. Phillips) and she mentioned Mugwort as a great dream enhancer. Cool. I thought. I’ll tell @CasLyn! Glad I scanned the replies. 
Of course, Caslyn mentioned she already tried it.
