A Dream (n.) is induced in us by bodily and mental inertia.
The Dream (n.) is so wide awake or consciously alert as the person who has to observe a dream.
The Dream (n.) is still at work revenging itself on experience and rearranging it in terms of desire.
The Dream's (n.) therapeutic role must ultimately be that of enlarging vision: it should be interpreted on the same principles as works of art: observe faithfully (literal), note all references to external events (allegorical), place in relation to your own libidinous urges (moral) & then aim for anagogic completeness.
The Dream (n.) is the digestive process of the mind. They rearrange the data (food) of experience into the libidinous form of either a cosmic resolution or an 'anxiety' tragic one.
The Dream (n.) expresses desire, concern, warning, quite genuinely, but always in slightly oblique language.
