I have wondered whether this idea is possible for a long time. I have heard a lot of people that say, lucid dreaming is easier to achieve once you have had one. And I know this is true first hand, or I'm just really good at it
But heres my idea- can you summon your subconscious in your dream and tell them to notify you when you are in a dream so you can become lucid?

In other words, can you get your subconscious to tell you that you are dreaming when you are in a dream to increase your chances of becoming lucid, or is that expecting too much from my brain?
