Welcome to DV

It sounds like you're already off to a good start.
In answer to both your questions,
Yes, but it depends on a few things. Learning to stabilize and also to really focus on the details will help keep your dreams very realistic, and working on dream control will help you summon whoever you want to fuck in your dreams.
Best way to do this is to just read and think and practice as much as you can during the day, imo.
