First post here.
I've been trying for lucid dreams for quite a few years now too, and I've even managed to have a fee myself. But I can never seem to do it when I want, it just happens.
Recently, while looking through a book of spells, I discovered the herb Mugwort. Along with seeming to help boost psychic abilities, and some health benefits, mugwort is also used to help achieve lucid dreams. just Google mugwort magic for more info.
