Of all these weird creatures
Who lock up their spirits
Drill holes in themselves
And live for their secrets
This is a metaphor for how the Aliens would see us living from up above. We lock up our spirits by sometimes hiding who we are to fit in. “Drill holes in themselves” probably alludes to how much we hurt ourselves through things like Drugs, Alcohol, eating bad food, and making stupid decisions. “Live for their secrets” is an illusion to how we, as human beings, are susceptible to things like gossip and suspicion.
