Dream About Mysterious Abandoned House

I had a dream where my mom had just bought a house for our family (me, my mom, my brother, and my sister.) It was a beautiful and still furnished home. There were three bedrooms. I helped my brother find a bed that was comfortable for him and he fell asleep. I also found the master bedroom and designated that room to my mom. I then walked into the third bedroom and noticed that it was still very much full of life. There was vibrant decorations still up, memories and arts and crafts on the walls, trophies on the selves. It felt like a young person’s room and it was decorated similar to my taste. The bedding was still there which was strange. I decided to try to sleep in the room but something was gnawing me to explore it deeper. I started to inspect the room closer and noticed that the computer in the corner of the room was really old. It looked like it belonged in the 90’s. The computer had a rounded back and it still had Windows XP running on it. Why had the prior occupants rushed out and left so many personal belongings? That was odd to me that things seemed frozen in time 25+ years later. Why had no one lived here since then? Is that why my mom had been able to afford the house? I then started reading some of the journals that were still left on the desk. In one of the journal entries, the prior occupant of the room had detailed paranormal experiences. One of them included a severed hand that had grabbed a visitor once and had scared the children on numerous occassions. There were a lot more entries so I gathered what I could find and rushed downstairs. I found my sister still awake in the living room and showed her what I found. My sister confirmed that she sensed there was something off about the house, she kept looking at the corner of the room where she couldn’t see anything but sensed there was something watching her there. I closed my eyes and put my hands up infront of me to sense the energy of the house. I did sense that there was dark energy around me, and set forth a force field of protective light around the house in the effort to expel the darkness around us. It lasted temporarily but I could feel the dark energy coming back into the house. I deducted that it was likely because the dark energy had a strong and long term attachment to the house and that’s why my protective barrier wasn’t holding. I held my sisters hands and asked her to set intentions of light surrounding her. She did so and our protective energy was stronger, but I could sense the dark energy was fighting back. I realized that we needed my mom as well. I called her over and the three of us held hands and we casted light around us, and my mom's energy was so powerful that this time, it stuck! I realized that it was possible that the dark energy would still to try to come back to the house so I told my family that we should only stay at the house for a short time and try to back out of the sale. I was also interested in investigating who used to live here and to see if we could find out more about what happened to them and see if we could meet them. The dream ended after we deciphered who the author of the journal entries was and were trying to figure out how to contact them.
