Dream About Friend Disappearance And Creepy Ceremony

One of my friends wanted to stay the night at my place, not sure who but I know they were a friend They said they needed something from outside so I was like ok and I let them and they went outside to grab something. a hour had passed and they didn’t come back so like... I was there like What if he got murdered And i went to the police about it and they were like... we don’t believe you So i had to prove it So I was sat there brainstorming in my living room and I looked outside and saw the neighbors idk why but my brain told me it was their grandsons they looked in their early 20s and they were riding motorcycles Anyways I went out and asked Have u seen my friend and they were like nope but they looked rlly sus so I was like ??? But I was like u CaNt JuDge A bOok by iTs CovEr And they left but they were angry and said ~ but don’t go in our backyard So I was like Oh? So I did after they left and found a giant field of lines of tiny grave stones in their back yard they were like two inches tall and about 6x3in like laid on the ground And I had to go around and find my friends grave stone I eventually found it and there was like a ceremony starting Where a bunch of people girls with white dresses and long black hair and boys with black hair and white shirts black pants came out Only the girls were holding candles But they started coming up the lines of graves and I had to fucking book it So I ran back to the house and on the way out of the yard the same boys were there and they said, “oh are you here for the ceremony?” And I nodded and they said, “oh I’m sorry for your loss” and then I walked past them and my dream ended there
