Thread: Inverse RC: 'This Is a Dream'

I'm currently reading Tenzin Wangyal Rinpoche's 'The Tibetan Yogas of Dream and Sleep', and have reached the practical part, whereby it outlines how to become lucid. Rather than asking yourself whether or not you're awake at frequent intervals, it recommends reminding yourself that you're dreaming. By this it is referring to the Buddhist concept of emptiness--that everything in our world is empty of inherent meaning and is merely a projection of our mind (things still exist, but what makes a chair a chair isn't the chair itself but the mind that observes it).

I completely agree with the concept as an aspiring Buddhist, but what are people's thoughts on its efficacy as a reality check?

Here is some of the chapter:

"It is as follows: throughout the day, practice the recognition of the dream-like nature of life until the same recognition begins to manifest in dream. ... The emphasis should actually be on you, the dreamer, more than on the objects of your experience. Keep reminding yourself that you are dreaming up your experiences: the anger you feel, the happiness, the fatigue, the anxiety--it is all part of the dream. The oak tree you appreciate, the car you drive, the person to whom you are talking, are all part of the dream. In this way a new tendency is created in the mind, that of looking at experience as insubstantial, transient, and intimately related to the mind's projections. ... Eventually this understanding will arise in dream and lead to the recognition of the dream state and the development of lucidity."


I'm struggling to see how seeing everything as a dream will lead to better recognition of a sleeping dream.
