There was previously a Schumann Resonance quantum energy pendant in the store which might help, which Dream will remake into a tag version for Teespring.
From the description:
The Schumann field set will help to induce an alpha brainwave state and vibrates your energy body totally (whole system along with individual chakras) the feeling is sort of like a vibrating from deep inside pushing and radiating outwards.
One particular effect we have noticed with this is that it help make out of body experiences/astral travelling easier.
