Sometimes when casting spells they can attract all kinds of energies around you. For example spirits, spirits or spiirtual entities can be attracted by energy coming from you and into the spell. spells can attract all kinds of things, no matter what the spirit may be. I have had a few spiritual entities with me when i did protection spells or cleansings. It dose feel creepy at first espically if you don't know them or your just not used to spirits But over time you get used too it.
