it kindas sounds to me that someone had something in their life that they adored dearly, but have been living w/o it for sometime and is still trying to fulfill the emptiness. Now it seems that they're realizing its time to move on & to stop dwelling on the past & focus on the beautiful things that CAN happen in the future without it!
И еще чьё-то понимание:
I'm almost positive it's about a person who has just committed suicide and can't go back. She's reflecting on the fact that she forgot so many things she might see in life, but as the overdose takes effect or the blood drains without end she can't turn back.
This is the best fit for the lyrics that I've found, and it means very much to me. I'll go through a more explicit analysis of the lyrics sometime, but not right now.
