Non-autonomous methods of entering lucid dreaming are various types of external influences that are able to help put a practitioner into lucid dreaming state. Computer programs, devices, various physical actions, the aid of a helper, or even chemical substances are examples of non-autonomous methods. In rare cases, these methods actually help, while some hinder the possibility of a genuine lucid dreaming experience.
Never count on a magical substance or machine to automatically eliminate the difficulties associated with lucid dreaming entrance. If such a substance existed, the whole topic of lucid dreaming experimentation would exist at an advanced level of development and prevalence in society.
In actuality, there are no devices or methods able to consistently provide access to lucid dreaming state. At best, these exist in a largely supplementary capacity, and the more a practitioner is able to do on his or her own, the more helpful and effective these supplements are. If lucid dreaming entry has not been mastered autonomously, then results through the use of supplements will be totally accidental.
The reason behind the weak effectiveness of non-autonomous methods of lucid dreaming entrance rests in the fact that the physiological process responsible for lucid dreaming experience cannot be exactly defined. Only generalities are known, nothing else. In order to gain a clear understanding of the state, the processes that give rise to it must be discerned and analyzed. All existing technologies have either blundered down a clearly mistaken path (synchronizing the hemispheres of the brain), or traveled toward the detection and use of indirect indicators (cueing technologies).
