The interpreters of the visions generally said about the vision of light in a dream that refers to guidance and repentance and about darkness refers to misguidance and confusion.

So that's mean you should choose what you feel is good , I think everything is clear , I don't know which religion do you believe , I respect all heavenly religions.

Remember that vision is either to be warned or to express you. I wish the best for you and God bless you . If you need any advices just ask me
