Be not afeard. The isle is full of noises,Sounds and sweet airs that give delight and hurt not.Sometimes a thousand twangling instrumentsWill hum about mine ears, and sometimes voicesThat, if I then had waked after long sleep,Will make me sleep again; and then, in dreaming,The clouds methought would open and show richesReady to drop upon me, that when I wakedI cried to dream again. (III.ii.131-139)
When I read these lines again, I realized that many of these sentiments are also expressed in "Hung up on a Dream."
The sounds in both are expansive ("The isle is full of noises" "A sweet vibration seemed to fill the air"). Both narrators experience a dream that directs their attention upward ("then, in dreaming, / The clouds methought would open and show riches" "Until I woke up only finding ev'rything was just a dream... [of men who] showed me strangest, clouded sights above"), and they later desire to experience this dream again ("when I waked / I cried to dream again" "now I'm hung up on a dream"). More generally, both pieces also describe the calming effects of sound ("Sounds and sweet airs that give delight" "sounds unheard... which gently touched my aching mind / And soothed the wanderings of my troubled brain").
In Claes Johansen's Hung up on a Dream (p. 30), Argent explains that Shakespeare's "language spoke to me; it had an indefinable, spiritual quality." In this instance, it seems to have influenced Argent's own words.
