Do you believe that all characters in your lucid dreams are parts of your mind or do you believe that dream walkers, angels, dream guides etc....

I have wondered this for ages but last night in one of my lucid dreams i was in this house and this boy was smiling at me and i said your not a dream character are you and he was like no and he seemed real. But that could be that i expected him to say no and act real so therefore he did.

I have got a feeling there are going to be mixed views on this topic.
