While I wouldn’t say believe No or Yes yet, I’ll say I thought of this myself before and At least used to believe its possible and put some possible such in my house to help clear and prevent haunting stuff. Any general Magickal ward or protective object or protective active entity could be said able to do this if wards exist effectively.
I also would say don’t take what anyone says things are as concrete without experience and much research (questions like this are good), especially with these topics where there’s been much debate.
There’s many beliefs in this growingly studied and theorizing field full of people who define and believe things differently, some believe entities can be in the physical, some say they will only go to the physically associated places in the astral to “manifest” here. Some say the etheric is the “upper” physical, some lower or upper astral, or even lower or upper mental, some say above that even, it takes research no matter what to Know because of the semantics, some Say without knowing, or Know without saying. While i’ll say all aren’t equally trustworthy, so just research. Maybe it IS the upper physical, maybe one can utilize it without knowing exactly even.
Some believe there is a unique astral space and a unique mental space associated with any outward/physically local location (as ones Current house), as well as a personal astral space and a personal mental space basically that are our bodies or internals within those greater regions (the astral and mental planes), where we (our astral/mental bodies/awareness) wander in/out of/about and can be affected from, along with entities at various levels we might not always notice or be affected by. From what I know the astral is said to be generally where one level of the world works and is affected from, and that a finer or greater part is affected from the mental, and that things in the physical manifest first from the astral, and from there first the mental (in same beliefs as some say the physical is within the astral, and the astral within the mental (or causal as sometimes called).
Along with these beliefs, its plausible if an entity has a person they see from a random dark astral space they’re in, or a mental space even, they could follow people back to their own local astral space of their house (or mental) and affect that person or people around from there (if they can affect us and we them), and so wards could at least Maybe make it a harder or slower time for the entity to do such (by say kick them out, by targeting the entities own astral or mental bodies, by pain, distraction, energy taking as stated, sigils, charged objects, or servitors could for example). If you feel it might be good to put those even theoretically or attemptedly, I can’t see how it would hurt compared to the other option. (Excuse my length please, I apologize as always).
