When you’re lucid in a dream, how does it feel? Does it feel just like when you’re awake? Or is it more “blurry”?
It really depends on how aware you are.
When I experience lucid dreams of a low lucidity level, I find they can be sort of dim and blurry. However in a lucid dream in which I am very lucid, everything is as sharp and clear as in real life (or course, waking perception can vary between being blurry and clear too 
)
I am locking this because there is already another recent topic with the same question.
How realistic ARE lucid dreams?
You should find some good answers there already.
