Fall in love!? A dream does not have to be Lucid to 'fall in love' as you put it. I don't recall ever having had many inhabitions about 'falling in love' in my non-lucid dreams when I had been a younger man. In fact, when I did begin to develop Lucidity, it helped me NOT to fall in love quite so readily with the fairer dream characters, as 'falling in love' would only tend to wake one up prematurely.

Also, being Lucid is not a guarantee that you can do anything you can imagine. Just today somebody posted of being able to fly away in a Lucid Dream. Control is never absolute. And if the Lucid Dream feels that you are overcontrolling things, the Dream will, with a mind of its own, try to throw you off with False Awakenings -- to shake off that "I am dreaming so I can control everything" mentality.

What Lucidity does offer is an array of choices and a certain knowledge that is not entirely available otherwise (though it becomes habitual over the years) and that is a Fearlessness which comes of knowing that one cannot die in a Dream, and also the sense that one has more freedom to move from one Dream Scene to another when dreaming... though I suppose that in real life one is also quite free to walk out of the room anytime one wants, though it may eventually lead to a quite shakey employment resume.
