I am new to witchcraft and find that when I'm performing spells I become afraid of doing something wrong, or not having clear enough intentions, and worry about the consequences of that. Also, every time I do altar work I feel like I'm not alone and unnerving things happen (ie. things falling over, music stopping etc.) I'm thinking of casting circles before my spell work so I can feel safer. I'm wondering if anyone has had similar experiences and what they did to make it better.
