Almost every one of my WILD dreams begins with me arriving in
Dream~World™ on the floor of my bedroom. From there I have to make my way out into the rest of the place then out through the door into the real world (if I so desire). So I know what it's like to be totally alone in an LD.
It's not too much fun though. That's why I try and make it out the door as soon as possible. That's when the fun begins because I never know what's behind that front door.

Side Note: One time I spent the entire lucid dream sitting in the living room watching tv. So yes .. LD's can indeed be as boring as RL (real life).
