Your close... At least in my experiences.

My friend, ALL Dreams have the potential to feel "real". However, in a regular Dream you can only remember that it felt real. In a Lucid, you know that it feels real. Objectively, I would say that neither is more "real" than the other. Subjectively, I would have to say Lucid Dreams are more realistic because you can stand there and think to yourself " Hey I'm Dreaming", whereas you could not do that in a regular Dream. There is also a greater chance to remember Lucid Dreams rather than regulars, so they feel more real in that manner as well.
