Welcome to dream views! : D Not everyone has a dream guide. Only those who give attention to it or are randomly guided by a dream character. If you want it to come out you can call to it or go to a room and expect them to be there. You can even try the dream phone or just imagine them appearing in front of you. If they dont come out you dont have to think too hard about it. Just try and if they dont come do something else in the dream.

About the soul/spirit thing you can appear as one in your lucid dream but I dont believe that you can go out of your body like in a OBE or AP. Other people have other opinions/belief about it though.
