Dream About Finding My Sister In Dark

I went to mine and my sisters old secondary school with my boyfriend. We went to find my sister, and when we went in the building it was dark and we couldn’t find our way around. Then someone came up the corridor and it was my sister. The second part I remember is driving down a local road I live nearby. And then I got halfway to my destination and decided I didn’t need to go anymore and started to walk back. There were 2 girls walking by me on the walk. They were talking badly about their friend and their friends hair product. The last part I remember is my dad sister and I were in my dads old house. We were swapping bedrooms. My bedroom looked the same as my bedroom in my current home but the walls were blue like they used to be when I was a teenager. I then said to my sister we can’t swap rooms as the bed will break if it moves but she wanted to try anyway. That’s all I remember
