My roommate and I keep late hours and her schedule often throws off my sleep, so I decided to create a crystal grid in my bedroom to help reset the energy. I used amethyst clusters at the four corners of the bed, a selenite wand across the headboard, and rose quartz in the middle to keep the energy gentle. I could feel the shift within a couple of nights, almost like the room became quieter. Since I've been into crystals for over a decade, I try to balance practical placement with intuition. Do any of you incorporate black tourmaline in a sleep grid or is that better suited for grounding during the day?
