i think this dream may be about you.
did he show you different rooms in the house? each room can symbolize a different aspect of yourself, with the house representing the whole. just as your body houses your soul, a house can also symbolize your body.
the books make me think of 'chapters' in your life. different stories. or perhaps the books represent the mind, thoughts or ideas.
the scar, may be representative of painful events in your life that have left you with psychological or emotional scars.
are you consciously exploring your 'self' right now? working on self? if not, then this dream may be suggesting you start to do so.
the man could even be a 'guide', assisting you on this journey of exploration.
cool dream
