Can't really think of anything else to do right now, so might as well share a concept I submitted to the survey
A psammead (wish granting sand fairy) that could possibly be combined with the idea of the sandman, putting people to sleep with magic sand and making their dreams (or possibly nightmares) literally come true, though maybe only for a short period of time. Ground/Fairy type
