Bring out the connotation in 'Or snorted we in the seven sleepers' den'?

In John Donne's "The Good Morrow" 'seven sleeper's den' refers to a Christian ancient legend. Seven Christian youths had taken shelter and enclosed up in a cave to escape the persecution of the Roman Emperor, Decius. The Roman Emperor ordered that the den walled up so that the youths would starve to death. But these youths fell into miraculous sleep and woke up after 187 years.

          Here, in this poem Donne uses the myth of the seven sleepers to amplify the poem's central idea. Donne suggests that before they fell in love his mistress and he were not actively living; they were only sleeping but they have woken up at last and perceived that they belong to each other. By this conceit Donne not only epressed of their intense physical passion but also represents a true spiritual incitement of the lovers' respective souls.
