Two questions from Russian dreamer

[Straight]

Hi everybody. My name is Ilya (Илья, that's male name). I'm from sunny Siberia. I learned about LD ten years ago or so. Since then i've been practicing it from time to time. Now i have one LD per month on average. More or less depending on how hard i try. Russian LD community is much smaller than English-speaking, so i decided to ask here: 1. Is there anything like lucid delta-dream? Is there a possibility to keep consciousness all night long? 2. Did anyone try to remember his real life during LD? How it affected on LD? Actually there is one more What excites me most of all about dreams is the fact that when you are dreaming (not LD) you don't feel strange about what's going on, you don't see any uncommon even if that dream is crazy - as you remembered when you awaken. When you "there" you are a part of that world. Like you have always lived there. And still "that you" is actually you. I dunno... It's hard to explain it even in Russian and my English is not good... But i believe you'll catch my thought. A there any explanations of this phenomena?
