Interesting post and topics, two of my friends and myself have mastered lucid dreaming to an extent as well as meditation, when we started we would look at our hand palms every five seconds to create a habit to help us enter the rem world and do what we pleased or to practice being conscious in it. until we were able to step out of our bodies and explore this world.
