Something came back to my parents' house

I live about 8 miles outside of New Orleans, in Kenner. Back in the 1990s, we had several paranormal experiences, from turning off and on lights, hiding objects, knocking on doors and sights. One time, the dog was barking in the hallway and I could see a mist emerge. I'm getting goosebumps writing this. All the activity stopped when I asked a paranormal company for help, in an email, and I was disconnected from my dialup, never to return.

I've been back with my parents for a year now because I cannot return to my home in China, because of the virus. Now, an old girlfriend came over, two months, that knew nothing about the activity in the 1990s, and told me she saw a dark figure poke its head out of a doorway. I began crying immediately. I didn't want this to start over again. Nothing had happened until about two weeks ago, I would hear a faint moaning. It sounded like it was coming from outside. I would always hear it during the day while on the computer. I paid no mind to it. Then, two days ago, I was home alone with the dog and I hear the moaning coming from 5 ft away in the living room, during the day. I freaked out. I couldn't see anything and the dog didn't react, but she's deaf now. Then last night, I was alone and I heard the moaning by my door. I thought it was my dad joking with me. I got up and realized I was alone. I don't know what to do. I called the priest to come out, and the priest did his thing. Nothing happened. Later, I was outside working on the card and heard it again. It's getting louder. No one but the dog was inside the house.
