Hey, Tyler! Welcome to DV

1. LDs can seem as vivid as real life or sometimes they are described as more real than real life since it is all in your mind and you aren't bothered by outside stimuli. It depends, though.

2. It's possible, but it depends on how... connected to the dream you are, how lucid you are. You can be lucid and have no control whatsoever, though.

3. Even though I'm not the most proficient at having LDs, I would advise two things when it comes to learning how to control your LDs: practice and confidence. As you become lucid mroe often, you'll learn what it feels like and learn how to do more. One of the keys do doing anything in a lucid dream, however, is to know that you can do whatever you desire (within reason). If you want to fly, don't stand there thinking about it; just jump in the air and fly or however you desire. If you want to find someone, either turn around or walk around a corner and know that they will be there.

Don't worry about it too much. With practice you'll do just fine. Let us know if you have further questions.
