Maybe you don't sleep deep enough, because to me when I sleep I for sure don't feel the passage of time, most of the time it is instant for me, from the moment I lose consciousness to the moment I wake up. In between those moments there's nothing, no visuals, no sounds, no feelings, nothing, unless of course I'm dreaming but that happens quite rarely for me.
