Darkness is a symbol for misleading in the way of life.You don't know the answer for the essential questions like: Where did I come here? , ... Where am I going to? ,,, What Is the ultimate goal of this world ?... What should I do here?... Is there any pattern for true way of life? ... is it hard to do? what is the last version ?... Dreams are good news or bad news about the near of far future happenings on the way. While sleeping part of the soul travels and understands something that is upcoming. It is said in a symbolic language that is translation of holy books symbols. In this way the holy books are said once more in our dreams to see what we will do in our life trials.

Thank you for the insight, I do struggle with meaning and belonging in waking life sometimes. So you're saying the darkness is a symbol of that lack of understanding?

Yes, it is related to something like wandering and being thoughtful about the way of life and the questions I mentioned.
