After breakfast in camp we joined Wilder and the shaman on a boat ride up river to the villages to look for some fish to buy. Apparently they didn't send enough food to the camp for everyone. After going to two different villages we still couldn't get any fish but we did see a sloth and a few cool plants, one of which had leaves that reacted by curling up whenever you touched them. Wilder got a bottle of honey for us from one friend and at another village his buddy let us dig up his yucca trees and get the tuber roots, the edible part of the plant, he also gave us a giant squash he grew that we could us in a soup.While on the way home Wilder told us about his experiences with the poison sopa frog, a frog that excretes a paralytic toxin from its back when threatened by an attack. The tribal people of the Amazon found that by getting the toxin into the blood stream, usually by burning their skin with a lit stick and then scraping the wound clean and then placing the toxin on the exposed area, purges the user of almost any other ailment, including blindness, cancer, ulcers, tumors, parasites, etcetera and they have used it for all these things for centuries. The user feels an immediate flushing of the face, their skin swells, throat closes a bit, they vomit and cramp up as they begin to sweat profusely.We had heard about this experience before and asked Wilder if we could get it somehow. Wilder said he knew a guy and that it would cost us 150 soles, or roughly $50 each for the experience. He said it would be ready by tomorrow morning, before or after breakfast. When we got back to camp Wilder also asked us if we would be ok with the Englander joining us for our ceremony tonight. Neither of us objected to the idea. We had lunch and talked to the guy, his name was Jamie. The German couple left when lunch was finished.Night quickly fell and we laid awake in our beds waiting for the ceremony to begin. Wilder had left with the Germans to tend to office business so a new guide came to the hut with another helper from camp after we had already drank and started the ceremony. He introduced himself as hiener and then went into the story of how his powerful grandfather shaman was killed by jealous bruhos, witch doctors, and that this type of thing was very common in Peru. He told another ghost story and then left with the helper when it was quite clear his being there was not positively aiding our experience.Soon after they left I vomited and neither Blake or I had any visions. Until the ceremony ended and we went to bed that is. It was there that a dark energy brought our thoughts into a completely negative space. It was already 3 am, I was dozing off in a nightmare like haze when Caesar shook me awake in my bed and whispered in a snake like hiss "espiritos muerto muerto muerte!" The spirit of death surrounds us, I told Blake what he was saying and He muttered a low grunt in obvious acknowledgment to the situation. Caesar took me back out to the ceremonial space and again performed the cleansing ritual on me, then he took his cot into our room and slept with us. The dark visions ceased and we all went to sleep, only a little shaken up by it all.
