Only mugwort really. But I've had significant results with sleeping with an Amethyst gemstone underneath my pillow, inside my pillowcase. Made my dreams really vivid, had many dreams, felt more sleepy, also felt like I was aware throughout the whole night. Like the whole night was in slow motion and it lasted as long as a day. Hard to describe but definitely worth trying. I've even reached lucidity from it as opposed to Mugwort which only got me lucid once. And it wasn't necessarily because of it since there are many variables.
