Lucid Dreaming

In the lucid dreams I can go to places no one has experienced yet.  I have asked about other lands from father's friends, and as they are great travelers I assume they would know better than most.  In my readings it is the same - there are no cities with the kinds of structures I have seen.
I am still wary of being caught in this state, but I cannot keep from exploring further.
