Yes it is possible for it to feel "more real" than real life (for lack of a better description). It is hard to explain, you just sorta have to have one.

And yes, lucid dreams (and even normal dreams) can be extremely vivid and realistic. Of course, they can also be quite hazy and blurry. Various things effect this. Some easy ways to boost vividness is to eat certain foods (you can find which ones help with a little searching).
