Thank you :-). And could anybody explain me what these words mean?

Never again, will I smell your sweet dream
But a pissed stained ol' gutter where…
You lips used to be

The first and the third line I do understand, I've found words of line two in my dictionary, but all together it doesn't make sense to me... I'm afraid it isn't anything nice, but I want to understand it. Thank you all for your help.
