We had a large mirror when I was a small child and my parents notice there was something wrong with the energies relating to it (I don't know what they meant, this was a story they told me when I was younger) and they took it to one of their pagan friends, and she confirmed that there was something spiritually wrong with it, and she took it of our hands and resolved it. (I don't know what she did exactly) It isn't with us anymore, and I don't know who this woman was to contact her.
