All that I can remember of this dream after forgetting most of it after failing to record it earlier, is that it was clearly inspired by the IT movies & it involved a possible It-like entity who could possibly possess / manipulate people, and this assumed entity was scarier than It in my opinion.
This assumed entity was in a certain unknown town, like in the IT movies, a group of young people had faced it once, but now it was many years later where they were somewhat old & had left the town; but in the dream they returned to the town to visit it.
I had more dreams but I did not record them and this dream was much longer, but I have forgotten most of it.
All that I can remember of this dream now is that the dream possibly took place in a slightly fictional version of The city of D, there was a fictional version of The BP Alternative School that had some fictional structures and buildings and a walkway behind it, and I walked through the back walkway and buildings a few times in the dream.
I had a dream that possibly involved my female coworker JB, maybe Alanis Morissette, and a somewhat older female musician with light-color skin with gray/yellow hair whose name I can not remember.
The unknown female musician had gotten a group of fans together to make a music album with her as part of an experiment, the fans played the instruments et cetera, and she did the singing; and the music album was recorded in a large room.
