Hello Vicky:
I just saw this, kind of late, just as well, since some of the stuff I have been dealing with might've influenced how I responded.
That said,
, I'll speak of what I have been going through, just in case it does relate to some degree. If you can communicate with people, then you can communicate with all kinds of people. The same is true when you can communicate with spirits. It would be nice if you only had to communicate with friendly spirits, but that isn't how it always is while in this world. For whatever reasons, some unfriendly spirits have become aware of me, and try to mess with me (on an on and off basis for a number of years). This can happen even while I am meditating and feeling divine love and peace. Despite my connection to something higher, being in a body and this world makes my presence available to unfriendly spirits. If your energy sticks out more than usual, such unfriendly spirits are more likely to become aware of you.
The key to coming to peace with this state of affairs, is not minding that unfriendly spirits make contact with you. I've gone through enough to realize that they can try to scare and mislead me, but they can't infringe upon my free will. If I choose love and other positive things, that is all there is to it.
In a way, it is a blessing that they have tried to mess with me, because this has helped me see that I have free will and don't need to become concerned about unfriendly spirits. When they come around I don't become afraid, and send them love and try to convince them to change for the better. (there is also that energetic merger retrieval thing I've spoken of before, but that's another matter)
It is kind of a bummer that I can't receive information from spirit without having to figure out whether it is coming from a trustworthy spirit, but that is okay, since I can listen to my intuition, common sense and intelligence, dreams, and already know much of what I need to know. I certainly don't know everything, but perhaps right now I don't need to.
I say all of the above just to make the point that whatever is causing paranormal activity in you house, as long as you have freewill and are interested in love and other positive things, you don't need to be overly concerned about what is causing the phenomena you are experiencing.
If your Mom is causing it, the time factor might be a problem. What I mean by this is, the way she experiences time could be different than how you experience it. What may seem like a short time for her, might seem like a long time for you. What can you do about this?
I have heard loud noises as spirits entered my house on a number of occasions. Most of such occurrences have been followed by one of those merger retrievals I've written about before. When such noises occur, you need to remember to distinguish between a creaking house and something paranormal. There have been occasions when I hear a sound like a fist making a loud knock on the door when the above type of experiences have occurred.
I have never seen anything moved around. I have had the experience of some unseen thing causing movement on my bed. There was an occasion when I felt a spirit touch me on my left shoulder, as if a person had done so.
A number of years ago I had the thought "even if an unfriendly spirit can't infringe upon my freewill, what if through poltergeist activity such a spirit did something such as drop a book upon my head while I was asleep?" I had a dream that made the point that I was protected by a higher level of being, and didn't have to worry about this. My feeling is that I have this protection because my heart, mind and soul are loyal to such higher, love-based level of being. If a person doesn't have such loyalty, perhaps an unfriendly spirit will be more free to do what it wants.
To sum up, we are in this world partly so we can be challenged with growth opportunities, including the opportunity to see that even when we are in a place where unfriendly beings lurk around, we are safe, and completely free to choose love and light. I don't mean to say that an unfriendly spirit is messing with you, just that whatever the case, you are okay, if that is what you want.
