I just had this theory in my head. The reason why lucid dreaming is so difficult to master is because the concept of lucid dreaming resides by default in the concious mind, not the subconcious. As long as it is in the concious mind it is very difficult to have them frequently. I figured a way that may be able to 'push' the idea of lucid dreaming into the subconcious and that is by suppression. But the person must already have the knowledge and concious awareness of lucid dreaming at the fingertips. You remember to RC when you see your dreamsign or feel like doing one during the day or walk past a door or whatever....Don't! No physical action reguarding lucid dreaming stuff, just passively acknowlege that you saw your dreamsign and know it's your dreamsign or know that you were supposed to do a reality check but you don't actually do it because you know your not dreaming now. By doing that the person is suppressing the idea of lucid dreaming from the concious mind into the subconcious because it was never concieved in reality/conciousness, just an impression. And when enough of it is suppressed into the subconcious, the person will get menifestations of lucid dreaming in dreams from about lucidity to being lucid. I can't explain how it actually works but I know it will just that someone with a better understanding of the mind may know what I'm talking about.... I will test it even though it dosen't make sense.
