I came back being your nocturnal

 I came back being your nocturnal. Soul that usually walks at night. With wings of emptiness. Flying randomly from fireflies. Fragile wings slicing through the silent air. Its effects, by waves, reach the other end of the universe. Its immense black background shining with the universe of fireflies. They reached the end and returned, endlessly passing each other in luminous friendly greetings.

Sense, then ex-isto as a hypo/thesis.
