Biodomes, Part 1

The speaker, a soldier, recounts a classified training mission where he and two others were summoned to a specific building on a military base. After being scanned with a strange wand and given a large white pill marked "877," they changed into tactical gear and entered a white, curved room. The room began to violently shake and vibrate, then stopped, revealing they had been transported to a massive biodome. Inside, they observed an exotic rainforest with unfamiliar plants, giant insects, and ate a unique purple fruit. The speaker believes such experiences, which he is now selectively authorized to share, are connected to broader phenomena involving non-human beings living among humans.
