Hi Jeanette!
Okay, I think I may have your answer. I ran your problem by a friend of mine. She is not only a Native American Shaman, but also a Druid High Crone. She makes and sells her own oils and herb blends, so she knows her stuff. This is what she told me.
First of all, Rosemary does induce lucid dreaming. However, when you do this, you are not sleeping as deeply as maybe you should. You should only use Rosemary to induce lucid dreaming once or twice a week with at least three days in between. To get the most out of it, less is better. The reason you woke up the last time with the phrase "Bride's Eyes" is because your body/subconscious was trying to tell you that you needed your rest. Bride's Eyes refers to her eyes the morning after the wedding night. She has been up all night, no sleep, and therefore has the dark circles. You must have heard this expression some where and stored it. Your mind used it to give you the message. If you lucid dream too often, eventually your dreams will become muddled and without meaning because even your subconscious is tired. I think that the reason you were up all night with the lavendar is because you had hit a point where you were basically too tired to sleep.
I hope this helps. Of course, she does not claim to be the end all be all authority, but to be honest, it makes sense to me. She also agreed with the person who said that an oil is much more concentrated that the dried or fresh herb.
Good Luck!
