Welcome to DV, Stem! First off, your English is just fine. If you hadn't mentioned you were from Poland I probably would not have known that you're not a native speaker. (I don't know if I can say the same for my Russian or Spanish... probably not.)

Anyway, that's cool that you had so many lucid dreams (LDs) when you were younger. Remembering what it felt like to be aware in your dreams might help you achieve lucidity more often. Mostly, just keep working at it and you'll have no problem.

Let us know if we can do anything for you. See you around!
