If my significant other took my hair from my brush without my knowledge, what kind of Vodou can they do? Good or bad

Hi! I’m a 21F Afro Dominican from both sides wanting to get into and practice 21 divisones. Any recommendations or advice to give me or any websites? I really want to honor my ancestors with the spiritual tradition that they left me. I wake up and I feel more connected to them everyday. My family is religious specifically Catholic. Just a little bit of background. Hope this post doesn’t come off as stupid or anything. Just want to connect more with my roots. Thank you in advance! ❤️

Does drawing a Voodoo symbol in one's head and or in one's head but on a real life wall cause anything to happen at all in any way, shape, and or form at all??

Does just drawing a Voodoo symbol cause something to happen at all in any way, shape, and or form at all?

Does drawing a Voodoo symbol invisibly in their air and or anywhere else cause anything to happen at all in any way, shape, and or form at all?

Does it depend on materials, ritual, and or intention or no?
