Just how real are lucid dreams in comparison to real waking life? Sensory and time wise?

Dreams for me always have big and small gaps in between them. Like, I can remember I was at my house, and then I was suddenly at the school, as though no travel time had transpired. I wonder if this is true in Lucidity as well.

Alot in my dreams, I can remember very 'fuzzy' parts that have either very poor vision, or scarce details of the surroundings. Like, I may recognize something as a convenience store in my dream, but not see the distinct details, like the way the neon glows in the 'Open' sign or even what colour it is.

Can anyone make a brief (or complex) comparison?
