Something like a cult

Date: 7/9/2019

My APUSH teacher took my class on a field trip in a swamp and me and my boyfriend went off from the group and found this huge tree with a door. So we crawled in it but it was really cramped so it was hard to even get in, but when we did we saw it was like an abandoned room and there was some guy made out of leaves and mulch. We thought it was fake but then it turned its head and looked at us and the tree started shaking so we freaked out and tried to get out of the tree as quick as possible, but that was hard cuz it was already difficult getting in the tree in the first place. The guy started moving but we finally got out and ran. Then the scene switched to being out in a field. There was a really pale girl in a white dress and she found this pit of red dirt so she went down in it and started digging cuz she found something. Then the dirt turned into thick sap or quick sand and as she grabbed whatever it was she was looking for, she saw it was the insides of a dead boar and the boar was all white which made the insides stand out even more. And then a bunch of pale people in white started to gather slowly around the pit and I guess they were gonna kill the girl or watch her die cuz she was sinking in the pit and couldn't get out.
