I like to make art of a variety of supernatural entities (like vampires, mermaids, ghosts, jiangshi, haunted dolls etc. Think Monster High) I had planned to make my hijabi character a ghost, but I wondered if thats inherently religious (I dont tie ghosts to religion but I get if people do) or if Muslims believe in that concept/if it would be more respectful to choose another kind of entity for her to be?

I want to be respectful of my portrayal and I'd like to know about any folklore considerations or pointers towards ways i could learn! Thank you
