It is also said that this crystal is a soothing and calming one. Amethyst promotes healthy sleeping habits if placed under the pillow before bed and may help prevent bad dreams.
One of the first crystals I bought was an Amethyst. It was in the tumbled variety and I never felt anything from it. Then a long while after buying the tumbled variety I ended up picking up an Amethyst crystal pendulum and that's when the Amethyst actually affected me.
I was lying in bed drifting off to sleep and for some reason I imagined myself inside of the crystal on my pendulum. Like I was lying inside of it and it was around me, I wasn't looking at myself in it but actually looking from the viewpoint of being inside of it. It was the absolute most relaxing and soothing thing in the world and it put me right to sleep.
If you're looking into crystals then this is a great one to have added to your collection. It's a versatile stone with many uses.
