The entire poem consists of two stanzas and of two varying significance. The first stanza deals with the world of living and the second with the poet's experience in the grave. The poet may be trying to be realistic regarding her death. She is against any sort of mourning that sings like of showing off. When she is dead, she won’t be able to hear any songs, see any roses, or feel the Cypress shade. Therefore, the best way to mourn someone’s death is by expressing the love as immortal as the green grass through the drops of tears as pure as the dew drops. It is also equally meaningless to insist someone to remember him/her after his/her death. Therefore, she gives her dearest one the freedom to remember of forgetting as he/she wishes. The poem also suggests us that no one can escape from the torturous grip of the death. If reflects a quite melancholic and inflicted heart of the speaker. - See more at: http://www.bachelorandmaster.com/britishandamericanpoetry/when-i-am-dead-my-dearest.html#sthash.QQHQJd3A.dpuf
