Ruby spots on a sheet

Early morning. I waked up,
Cause felt myself bit cold.
I saw strange juice in crystal cup,
And dropped an eye I hold.

Who was the girl, I see lies near?
I don't remember name and age+
Just eyes so deep, so blue, so clear+
And bell-like voice. Oh, bird in cage!

She was a light in my dark kingdom,
But I was drunk, lust poisoned mind.
I let her soul enjoy the freedom,
And now I see how I was blind+

+I cut my veins+ This eventide,
I'll follow you my sleeping bride.
