Is seeing the Prophet and seeking his intercession in a dream valid if the dreamer is in a state of major ritual impurity (junub)?

If the vision is a dream, then it is good, for the Prophet, peace and blessings be upon him, said: "Whoever sees me in a dream has indeed seen me, for Satan cannot assume my likeness," and he said: "Whoever sees me, has seen the truth." The state of ritual impurity (janaba) does not prevent one from having a righteous vision.
