Hello everyone! I recently found out about LD; it does nothing but amaze me of the possibilities, and now I'm trying to learn how to have them.

Got some quick questions:

How can you remember to reality check, when you're dreaming? If you remembered to reality check in a dream, you'd already be aware that you might be having one!

On average, how long does it take for someone to learn Lucid Dreaming and have their first decisive experience?

Does the way you breath influence how well you dream?

Is it possible to learn LD off by heart and have it whenever you desire?
