Lets see. It greatly varies on person to person and how lucid you are and such to what a lucid dream feels like. For me my first few dreams were a little airy and almost felt like a trampoline. While as I got more practice and such it started getting so realistic lately that it was scary. As in getting every one of my senses completely accurate to the point where the line between real life and dreaming was blurred. Your brain is a powerfull thing don't underestimate it.
