In a Dream

If I were in a dream and if I were to find my way out of this dream, would I seek help from people in that dream?
If I were in a dream and if I thought of this dream as a dream because others in the dream said it was a dream, would that dream really be a dream?

If all I have ever known is that dream, if I have not known myself without the dream, nor the dream without myself, would the dream and myself be two things?
