I have a question about what I am feeling after a spell casting. Usually a few days after a spell has been done, I will feel these cold rushes through my body. This is not like when you feel the cold air and you get goose bumps, this is a coldness that runs completely through me and is almost painful. I was told I am feeling the spell working, even though the spell is not for me, but for something or someone else. I have tried searching online and have asked a few people who said I was definitely in touch with my energies and that is what I was feeling. Can someone with more experience clarify? Thanks.
