I haven't had anything like these, but I can't have moldavite anywhere near my when I need to be functional. I get lightheaded and nauseous, and start seeing symbols in the air. I have had many many crystals disappear randomly and reappear in odd places. One of my quartz crystals likes to hang out with my stationary. I have never put it there.
Yes, moldavite is very powerful and when I first purchased my moldavite, I was getting migraines. I realized that I couldn't have the moldavite anywhere near me when I was sleeping, or I'd get a migraine headache and become nauseous too. I spoke with my then boss at the New Age shop,where I had purchased the moldavite and she suggested that I also purchase a Pietersite to wear with it. I did so, and it really helped. No more migraines. Pietersite is very grounding and should help you to open your third eye.
I also will say that the moldavite was very good for me when I was astral traveling and also making contact w/the spirits. I wear these two stones along with a good luck bead from Peru on a chain now, just about every day.
Stonesatiety, what a beautiful story about your smoky quartz!
I did have an interesting happening before I purchased my raw amethyst that I had been looking at. I kept admiring the raw amethyst every day that I was at work at the New Age shop, but never purchasing it. Finally one day, out of the blue, my deceased aunt came through to me and told me, "Oh for heavens sakes, BUY that amethyst!"
So, the next day I went into work, I did just that. I purchased the raw amethyst and I would have it out on my reading table. It really did help me with clarity in my intuition too--they became sharper and more accurate. But then, I was always drawn to the amethyst stone and I just love its deep blue colors.
