One who leads a life of dreamy, indolent ease (5-5)
I believe the answer is:
lotus-eater
(Other definitions for lotus-eater that I've seen before include "One given to indulgence in pleasure and luxury" , "One indulging in pleasure and luxury, as described in Homer's Odyssey" , "One living indolently - mythical person met by Odysseus in North Africa" , "Indolent person" .)
