Cryptic Conversion Cleaving Thy Entity

Strangers from evil caves must be researched
Dark and corrosive skin that can't be cut off
Five angled head, elastic form
Dressed like a surgeon, protoplasm on my arms

What was being here millions years ago
Born or war a new civilization
If they still alive, insane things in my head
But thinking that I've been seen, it scared me

I need help, I’m done, I leave it
Research must be fully completed

Even if I die I want to tell about this time
Another feels another desire
Another life

What was being here millions of years ago
Born or war a new civilization
If they still alive, insane things in my head
But thinking that I've been seen, it scared me

Even if I die, I want to tell about this time

Another life
