All men dream: but not equally. (T. E. Lawrence: Seven Pillars of Wisdom)
 
So indeed do all men dream. Of the future, the past, the present, of people, places and things. But of these it is the past which is evocative. Past time, seen in a dream, holds life to suit not as it originally fell out. 
 
The past is mostly prosaic. Ordinary time filled with the machinery of existence. A life slipped away from its moorings and travelled variously purposeful towards an end which is the present. Rearranged in a dream the past may yield riches in people, experience and wealth. Men may dream unequally of riches. Wealth is of the least value.
 
The past has its result in the present, the living creature in its situation now. But past circumstances might have been better understood, made more of, fashioned towards a different end. Men may dream unequally of ends, of degrees of grandness, of great moments made more plausible by the arrangements of imagination.
 
The past has gone but its legacy has not. In the unequal dreams of men regret may be lessened and fortune less abused. But sins may linger, blighting the penitent, overcome by the long-headed.
 
The past may be a past of regret, if so the past is wasted. Regret fills out experience. Men dream unequally of regret. Wisdom infuses consciousness when regret is left behind.
 
All past has ambition. The present yields the harvest. Ambition is the stuff of dreams. Men dream variously of ambition swathed in glory, buried in ridicule, misplaced in time, respected for diligence, decried in failure, honoured in modesty. 
 
Quietness of the soul eludes those whose dreams re-manufacture the vicissitudes of past time.
