It's difficult to sleep in the high 100% humidity. It makes for a listless night. The tribe I was living with had dogs. These dogs would bark when any living creature larger than a rat got near the village. This village was no larger than an acre, mind you. They were also in a perpetual state of warfare with a neighboring nomadic tribe that was even more primitive. The tribe I stayed with had converted to Christianity, yet still practiced their old ways. This rival tribe was known to be able to slip into the village at night totally undetected by the dogs and slit people's throats while they were sleeping. So I did worry about that. Someone did rummage through my stuff one night and I saw the barefoot footprints. They said it was the other tribe, but who knows. I was completely at the mercy of this tribe for my survival and had to trade my labor and an expensive LED flashlight to ensure my survival. They were extremely delighted and grateful I gave them that flashlight though. They taught me how to survive in the jungle. This deep in the jungle, aside from hostile tribes, there are also cartel operatives, guerillas, smugglers, and other criminal elements roaming around in the jungle at night. One night, not at this location, but in a different region, we were attacked and had to fight for survival. Do you see the mosquito net there? Often times I would wake up in the night and it would be completely coated in insects. Mosquitos, and a variety of other insects, some as large as your hand. Insect-borne diseases are the number one threat in the jungle. You don't sleep well in the jungle at first. It takes about seven days to acclimate. Still to this day, I can be sound asleep and hear a noise while I'm sleeping and pop up wide awake with an adrenaline rush and be ready to go. I call it jungle sleep. You're asleep, but also somehow awake and listening. If you don't gain this adaptation deep in the jungle it can be fatal.
