Friend lost in a sewer

Date: 8/4/2020

My friend Morgan and I were on a road trip somewhere and we stood in front of this like, giant tube that was there for some reason (almost like the opening to a big water slide) to take a picture. But then she fell into the tube and I didn’t know where it led to... I didn’t want to go in after her because it apparently was very dangerous. So we had a missing person thing on her and we were searching for her trying to figure out where she ended up. Eventually, after 2 days, I finally found her in the sewers in this big plastic cylinder thing. She could hear and talk to me (she sounded very weak) but I couldn’t see her and didn’t know how to get her out. Finally we got her out (I don’t remember how) and she was super dirty and smelly obviously. But apparently while she was in that container for 2 days all alone she had been like, meditating? And she decided she was going to live a different life, so she shaved her head and moved to the mountains.
