Black Entity That Comes At Night

I am writing to get some help and insight into what exactly might be going on, and what I might be able to do. I have very powerful intuitive abilities, and can see energies that go unnoticed to most, but I have never been very adept at psychic self defense. This is something I have been working on but now I feel I need much more protection than even that. Let me get to my story;

We (me, my 3 year old son and fiancee) recently bought a new house about 3 months ago. It is our first house, and we were all really excited about it. I knew something was up the first night we stayed there. As I was lying in bed, this energy system that Is nearly impossible to describe beyond it being multiple oval shapes interlocking and rotating around each other- floated toward me and proceeded to "check me out". I mentally sent a message introducing myself, telling it we were the new owners of the house and thanked it for allowing us to live peacefully there. Shortly after, the being dissolved away and I have not seen it again.

But since then, I have felt a more negative force in the house, and at night the house emits creaks and bangs which may or may not have a reasonable explanation. I've been immersing myself in esoteric literature, and the more I learn, it seems the more this force is working to stop me. I was sick twice with a stomach bug which no one else in the home got but me. I never thought of it as anything more than some kind of food poisoning. And then again, it happened last night. But this time there was more to it than before. This time, the night routine was different than normal because I couldn't sleep which has not been a problem for a couple of years, and that is a story for another post another time. Anyway, after trying and failing to sleep, I got up and spent a few hours in the living room reading and tried again around 2 am. I had the same uneasy feeling as if something was not right. Usually when I get this feeling, I find out the next day something catastrophic has happened in the world, so I tried to tap into it. But my thoughts just felt scrambled. Before I knew it, a large black entity was lying on top of me. I was on my side, and I could feel it, leaning towards "it" being a "him", pressing down on me. I attempted to shield my body with a protective bubble and call in my power animal and angels. I was able to find the strength with their help to send it flying off of me, but it just kept coming back. After a few tries, I switched my attention to building a more powerful protection around me, but I could see in my minds eye it was just turning into this black muck. I don't remember anything after that until I woke up a couple hours later and realized I did not feel well at all. By 8am. I was extremely sick and have been since then.

Maybe the 2 things are unconnected, but I believe there is a strong chance the illnesses I have experienced- one every month since living here are a result of this being, but I can't say what or how it is doing to me beyond that. I know its a little out there, but I think it is feeding off of me in some way or blocking my spiritual advancement. If any one of you out there has any wisdom to share with me involving this experience, please let me know. I want to understand what is going on and if there is something I can do. Thank you for reading.
