Thread: How much could lucid dreaming actually help you?

Since when your in a lucid dream you can speak to your subconscious, how far
could it actually help you.
For example if one had an exam the next day, then would asking your subconcious to recall information better actually work?

It would help if anybody could share results with speaking to your subconcious. Also,include what you asked and how well it worked, or didn't. I'm pretty new to LDing, so can someone tell me how to get to your subconcious in a dream, if you actually can.
