What you describe here sounds to me like
Scientifically this is known as REM your mind is going crazy and you are not quite asleep but trying to get to what your brain considers sleep. Those half hour naps can be awesome when you have the dream control. I can come home at 3:00pm and pass out for an hour and basically do what i want practice new recipes from food network. Do some tae kwon do or even just fly around for what seems like an hour. Sometimes i just lay there fully lucid for hours and fish. Ive never cought one but i always get bites. > could be fishing at the local pub you know its all up to you.

What you will dream is up to your imagination. From what i see there is no boundries

Note REM has nothing to do with attaining lucidity.. It can happen in a crazy non lucid dream or in a vivid lucid adventure.
I would think "you" of all people would be aware of this. This is sinning and bad things going on in your mind girl. Like me and my wild nightmare. Try praying at those moments, until you drop directly into lucid dreaming you might find yourself floating in clouds almost ready to reach climax with jesus at your side. May sound unappropriate or dirty but thats your mind wandering not mine.

Think Positive and maybe find something to calm you on those lonely nights.

Peace
