My family is very sensitive and also works with crystals alot. My grandmother could always see things and my mother sometimes when she blocked it. I've never really been involved other than some crystals affecting me (amethyst hurts when i touch it) and being able to feel other people's emotions.
I have just learned that my family had to place a seal on me or "shutting the door" as they called it, when I was young so I would stop summoning/inviting unfriendly things into our house.
My family refuse to tell me anything else about this and its frustrating...
I want to break whatever this seal is but my research isn't finding anything useful...
Can anyone help?
