Is it possible to talk to your subconscious mind?

your subconscious mind is always alert and listening even when you're asleep. My mother used to tell me when I was a kid (when she didn't want to talk with me about something; I didn't have any siblings to talk with and stayed home alone a lot) to talk to the mirror, to talk to myself and hear out loud what I was thinking then my ears would hear it and act accordingly, she said. What she means was that I should (as a kid) have an array of answers I could choose from to make determination on which road I should take to solve a problem. Of course she was wrong because I was just a kid and didn't have that array of answers at my disposal, but she was trying to tell me to think for myself. So yes, it's possible to talk to your subconscious mind.
