Many years ago, I was planting pine seedlings in South Carolina on a clearcut/ burn site that was known for having nice crystals. The ground was rotted feldspar with occasional bands of quartz. I would follow the bands of quartz, looking for facetted pieces & then dig crystals. One day, three guys came into our camp and told us they were professional crystal hunters. I showed them what i found and they begged me to show them where to dig. They offered me an ounce of weed for my time. I told them to come back in two days and i would show them where to dig. The next day while planting, I found a few crystals on top, picked them up and fixed the spots in my mind. The next day the guys showed up and i led them onto the site. They asked how I knew where to dig and i explained that i could feel the crystals calling me. When i got near the spots that i had found the day before, I raised my arms like Moses parting the Red Sea and started shaking and waiving my arms around and then would point at the ground and say dig here. They dug and found crystals. I played my part 3 times and each time they dug crystal. At the end of the day, they gave me an ounce of good weed and asked for my address & phone number. For several years after that, I would get phone calls from the "professional Crystal hunters" begging me to come show them where to dig. It sounds like your friend is playing with you like i did those guys.
