Dream Blindness

I've noticed ever since I had my very lucid dream last year, now I am still able to realize I am dreaming but I can't SEE anything. I try looking at faces and they seem either blurry or flickering in and out. I can hear them perfectly and they can here me perfectly too. Can someone please let me know a trick to increase my awareness of all my senses?

Next Question:Is lucid Napping a reasonable expectation? Or is it only possible to attain Lucidity after a period of deep sleep?

I am posting these question in the newbie forum as I suspect they have been answered before however perhaps not in the same way, so I ask you to forgive my ignorance and guide me.
Thanks,
EH

This happens to many people. All I can suggest is focusing on them more, or try slow dream spinning, rubbing your hands together. Maybe someone else will have more tips.

Welcome! I hear good things about hand-rubbing to increase clarity, or shouting "clarity!", "more vividness!" is supposed to work too.

As for naps, they're good for lucidity- provided you time it right. Check out this tutorial, it should help you.
