There was Old (village name), which was flooded. All that was left was the cross from the steeple of the church. The gang went out to investigate, and the village god started appearing. He was a lake god, who was a bearded man in a heavy hooded robe, who would be seen standing in the shallows of the lake, looking but never saying anything.
When the gang rowed out in a boat to the cross, they discovered it wasn’t actually a cross. It was just a T-shape or cross shape of metal. It kept changing forms, starting as a cross of rebar, then a T of pipes, and finally an antenna with a smaller dish-shaped antenna on it.
They went back to the village, and one of the teens went running in order to get in touch with the ghosts. This was in the neighbourhood where I grew up.
I/he passed a pile of stuffed animals on the sidewalk that was connected to an earlier dream (?) where there had been an abused child. The teen thought the stuffed animals had been rained on, and would be moldy, so he didn’t take any. At the end he was running through a paneled hall, and came out to say that the ghosts wanted all the sports the local high school played incorporated into the school cheer, not just football. He was told that he’d been gone for six weeks. The lake god was looking at him.
