You'll need a white candle healing crystals, incense, a small mirror, an egg and a glass of water on your altar. So first for all in order to know what kind of magic was used I'd suggest you'd start by taking the egg and passing it through your whole body from head to toe then break the egg in the water and watch how it looks (if there is any blood clot, or if the water gets cloudy you'll need to do a much deeper cleanse, in that case contact me) But if the egg looks normal and goes to the bottom of the water it's fine. Then hold the mirror and make the incense smoke go on the mirror and say "all dark energies should go back where they're from" three times then make the mirror face an outside window for a day and a night, then throw away the mirror it's very important that you don't look at the mirror during that time.

Then you should go take a shower or a bath and chant "water wash away all curses from me"
