Woohoo! Was struggling with
+qim rihh htni w fviwx vwty
+qeklq +qiv rwhh xwvnif +qi iyf er w fviwx
and getting
They fell like a dream rain
Though ther fall marked the end of a dream
by assuming +qi == the, but "ther" is a typo on the part of your friend, or where ever he got this.
The complete (correct) quote includes the above lines, from the first cipher I solved:

Petals and leaves
Dust and ash
They fell like a dream rain
Though their fall marked the end of a dream
