Is attracting entities that will physically harm you (not convincing you to do it, they themselves harming you) a thing in witchcraft?

Yes, I have religious trauma. And yes, I read the faq, similar questions and made my own research. As a baby witch I learn things day by day, but I just want to make sure of somethings before I really get into the craft.

Based on my research and beliefs; evil entities who want to harm you can only harm you in mental ways. This would take a long way to explain, but I believe physical aches, sounds etc. are caused by their mental, non material methods as well. I think the only way they can even make themselves seen is making the human believe that they are seen.

But this is what I believe and my research is based on what I believe. If I made my research from a highly positivist perspective and said that it was the truth, then I wouldn't be here at all. So what does witch craft(?) say about this? Or your experiences, beliefs, religions? Let's say that I did something wrong and there is an entity who wants to hurt me. Is it possible that it will come and jumpscare me like the ones in the horror movies? Throw knives? Or are we talking about coercion, paranoia, dreams etc. ?

I know fears are a frequent topic being asked, but it feels like everyone's just throwing pretty words around without giving an actual answer. "There are living things around us, protect yourself." Alright. I am studying protection right now. I love it. But what am I protecting myself from? What is the worst thing that could happen? Is there a clear answer, or is it based on my beliefs?
