Dream About Losing Child In House

Ian, his mom Linda and my daughter Lucy were in a trip and stayed in an home while traveling. It was a huge house split into different rooms but there were no doors and every room was connected. While exploring the house I realized I came across other peoples rentals and was very confused that there wasn’t a wall or door to separate the different living quarters. There was a pool in the house and in one pool it was very deep and had mattresses. Lucy had found a friend she was playing with in the pool. I was laying on a pool chair next to the pool. There were other parents sitting on the ledge where all of the kids were playing. I lost sight of Lucy and was yelling for her. There’s was a bunch of mattress in the pool and the pool also had fog on the top so I couldn’t see to the bottom ver well. I went under water to look for her and couldn’t see her. Then I started running around the house yelling for her and asking everyone if they had seen her and no on had. I was screaming and crying in my dream and I had this feeling that someone knew where she was but I also had tremendous guilt because I felt like it was my fault that she was gone because i waited to long to look for her after I lost sight of her initially. I was crying and accusing people at the house and they were just laughing and mocking me and I just knew they knew where she was, someone had her and I just screamed and cried and felt so helpless.
