I've actually had a run in with a negative entity in my waking life. I hesitate to call it a demon since it didn't seem angry, more mischievous but it was highly annoying.
About a year ago my girlfriend's aunt died in a horrible car accident (she was accidently run over by her brother-in-law truly horrifying). This was a very negative time for my girlfriend's family as her mom and sister's really blamed the brother-in-law for her death. Anyways, as her stuff was being divided up, my girl brought home a few knick knacks, one being a piece of dinner ware we setup in our kitchen as a decoration.
Not long after this, our dog started to get really worked up for no apparent reason. He would sit in the entryway into our kitchen with all the hairs standing up on the back of his neck and soft growl into the kitchen. Sometimes he would straight up bark for no reason and it was impossible to calm him down. We'd end up having to give him a sedative, and even as he'd calm down he would shake so we became concerned that something was really wrong with him. We took him to the vet and they were no help.
Awhile after this, my girl and I went to a psychic fair in town, the first one we had ever been to. I had a reading from a psychic that was pretty impersonal, yet when my girl sat down for her reading before even asking my chick's name the psychic said 'oh honey, you need to take care of your dog he's terrified at home!'
Clearly this rose a pretty big alarm in us since we knew what had been happening recently with our pup. The psychic went on to say that when my gf's aunt passed away, the negative emotions surrounding her death manifested into a negative thoughtform that attached itself to some of her items. By bringing in the dishware that my gf and I had done, the psychic told us we had inadvertently invited a negative being into our home. She told us the being wasn't strong enough to harm her or I, but our dog was closer to it's wavelength and could percieve this creature and it was tormenting our dog. She recommended we do a banishing ritual in all the rooms of our house.
Being born and raised Catholic, the idea of trying to perform a banishing seemed sketchy at best (I was always taught that any dealings with the occult were forbidden by god). However, having no other options or leads to go on, I said what the heck what could it hurt right? We went and bought sage as we were recommeneded by our psychic friend and burned it like incense in every room of the house, saying an incantation which I can't totally remember at this particular moment (I'm sure the internet has plenty to offer in this regard). We were also told to leave all the doors and windows of the house opened while we did this so the being would have a chance to escape.
I felt silly while her and I were doing this ritual, but wouldn't you know it the dog never barked again after that.
So, having said all that, here is what I recommend for you Ki. It seems as if your girl has a lot of negative emotional baggage. I've had several people in my life that have had a similar aura about them and, even against their will, they seem to be followed by negativity everywhere they go. I would suggest you lookup online a banishing ritual of sorts and follow the procedure I outlined above (or, better yet since I'm hardly an expert at this, look these things up online). I'd go through every room of your house with sage lighted up and try to focus on bringing light and love into each room of your house. Don't bear the being any ill-will, that would be counterintuitive (I'm told they feed on your fear and negativity since like attracts like). Instead, just kindly remind this creature that you bear it no ill fortune but it cannot stay in your dwelling any longer and wish it on it's way.
It seriously worked for me bro. All the best.
