Lojong is a practice the gradually cultivate the sudden awakening experience. Like a hwadu question that raises Great Doubt, the slogans are statements used are used to raise Great Faith. Both require consistent practice to have any effect on the dormant mind. The slogan "regard all dharmas as dreams" means that all conditioned phenomena are like dreams, they are dreams. They are of course subject to impermanence, but they are also interpretations--stories--that we tell ourselves to get through daily existence. They rarely go beyond partial perceptions of reality. There is no phenomena--a dharma--that is worth clinging to, as none have any substantial nature. Realizing this results not in Fear, but Faith.
To rest in the nature of awareness of the present moment--alaya--likewise gives great comfort. We realize there is the Dharma, we don't necessarily perceive everything completely accurately, but this is OK. This is all preparation for that sudden moment where all becomes clear, and indeed seeing this is part of the moment of awakening itself.
