I have been studying wicca and witchcraft for what seems like decades.
I have found that your crystals and or tumbled stones can speak to you through these vibrations. The very first time I purchased a crystal I sat on the sofa and opened the box with no expectations really. But the second I reached in to take hold of the crystal I too felt the goosebumps and chills.
As I held my rose quartz I smiled and closed my eyes and I felt I was floating. A strange feeling but I have had several older witches tell me that is the way it feels when you have discovered your calling.
Hope this helps.
