Darkness represents the "fragments" of a broken soul trying to find a way back to the light.

Mull3 - Снова ночь lyrics translation in English - Musixmatch

For months, Anton had been living in his own "night." After his relationship ended, he felt like the protagonist in the song—wandering through a "forgotten house," unable to find the light. Every sunset wasn't just a time of day; it was the start of a ritual where he would replay every argument and every "why didn't you stay?".

The "useful" lesson he took from the music was this: By accepting that the feelings were lost, he finally stopped fighting the silence. He realized that the dawn only comes to those who have actually walked through the night, rather than trying to hide from it. Key Themes of the Song

Acknowledging the "tiredness" that comes from toxic cycles and lost passion.

One evening, while the rain tapped against the glass just as it does in the song's verses, Anton realized something. The song doesn't just talk about the pain; it acknowledges how "tired" the soul gets from holding onto a ghost.
