I don't want to sound pejorative, but I'm genuinely impressed by how you managed to accurately perceive a glimpse of such a higher-order being and retain your sense of self. That shows rare fortitude.

This experience will likely aid you in two ways. First, it will likely lend a sense of relativity to beings such as the Leshy, allowing you to be less disquieted by them. Second, and perhaps more importantly: once you see something like that, you become able to more easily find it again. You may be able to detect something similar even if it's in hiding. Even if it's back on Earth.
