In her poem A Poet?s Love, the tranquility of the night seems to enhance L.E.L's ?world of dreams?; somehow it is the silence that leads to poetic vision. L.E.L?s dreams allow her to escape reality and drift into fantasy: ?I am fain, / Amid my life of bitterness and pain, / To dream once more my early dreams again.? We see a similar tranquility leading to drifting mental visions (dreams), in Samuel Taylor Coleridge?s
The Eolian Harp as well. Coleridge speaks of the ?tranquil muse upon tranquility:/ Full many a thought??
see here It appears that both poets have their finest visions when the rest of the world is shut out.
