The same way you get clairsentience and telepathic comms, you can do it, so can they. For them it’s thier primary if not only means of communication, so they’re very good at it.
If you think about it, communicating via modulated sound waves being interpreted back to implied meaning in the brain in a specific order is kinda cumbersome and can only work in the physical. Same with body language.
You need two things to do ‘magick’, you apply your energy to affect other energy via your intention guided by your attention. Energy follows mind.

Thanks for the suggestions 
very interesting!
I think the first entitity learned that I could hear them and then it passed the word to other spirits, ‘hey, this guy can hear us’.
Ok, I got it Unofficial Tutorials: Spiritual Hygiene & Defense Collection
I actually grabbed a pencil and I drew a real circle around while thinking ‘this is my space, anybody else… get the f out’ 
I was sick and tired of the whole situation.
This is puzzling. Why do you think an entitity can be aware of what we humans are visualizing? or projecting?
Once, a powerful negative entitity got into my head. When it got inside, I could see its form - not human. It wasn’t reading my mind, it was trying to take control. I didn’t let it.
The only reason I allowed it to stay in my head was because I was fascinated watching its strange shape and color. When I had enough of the show, I just kicked it out.
How can I kill an entitity? 
This would be great as a last resort.
My tactic right now is boring her. She made a huge mistake by yawning at me. If she yawns, it means she can be bored. So I’m boring her to hell. Whenever she has enough, she’ll hopefuly go away.
It would be great if I could set up a propper ward but the kind of entities I deal with, don’t care by anything.

Intend to burn it alive until it’s nothing but ash, use the visualisation to apply your energy via attention. You has zero intention of allowing the posession: take that attitude with you into the fight.
It doesn’t matter that this is symbolic: there’s no physical fire, your subconscious gets it and applies your energy to effect the desired outcome. So the trick becomes doing whatever is takes to get your energy flowing the way you want, and that is a skill. This is the entire point of a ritual, raising/gathering and then applying energy.
If that is your attitude, then you have made it so.
You’re the one in charge, it doesn’t get a choice.
Your one ward was not a ward, and weakly done. Put more energy and attitude into it, don’t just ask entities to leave, see them leaving whether they like it or not, there’s no asking or telling, you don’tleave it up to them, you push them out with your energy.
Like a drunk in a bar, you don’t ask, you bums rush him to the door then shut the door in his face.
There’s other methods, look up “what’s normal creating wards” tutorial.
