you mean have you seen one as though it was a real human? once or twice. while Rori is not one for listening to people, unless he knows i'll be so upset i'll tell him to leave, he's only appeared in front of me once [and my mom a few times] but it was so quick i don't know if i dreamed it. see, mom always had really bad nightmares and would wake up screaming, every time she said she saw either a girl with long black hair standing over her [i chalked it up to an obake] or a young man standing at the foot of her bed. i told her to keep her shoes pointing away from her bed [read once about a spirit/demon who followed your shoe prints to your bed to bring you nightmares but couldn't unless the toes pointed towards the bed.] and her door half closed instead of open all the way [Rori isn't a fan of open doors for some reason] she's done that ever since and has had no bad dreams. ANYWAY, the last time this happened i was returning to my room, i shut the door and turned on the overhead light and there was a man [early 20's] standing there [i remember he had glasses and i think short dark hair] i quickly shut my eyes and when i opened them he was gone. i think that was Rori, he's never appeared again, and whenever i see him he's a shadow walking around the room.
the other instance was when i was a child, my family use to go to our great cousin's bed and breakfast for brunch after church, then visit with them in their kitchen/living-room part. i still remember the place perfectly, by the window in this old rocking chair sat this old woman who use to tell me stories. when i got older, i asked if that woman still lived there, and my father had no idea what i was talking about, i described her, and dad said it sounded like a great aunt of mine who died before i was born.
so i have two stories about ghosts who where practically physical, but they have to be very powerful to do so. i don't know why my aunt was like that, i've never been back to ask, and i don't know if she's even still there. Rori says there's no point and he doesn't want to scare me. But Rori says that to a lot of things, he doesn't talk to me because there's nothing to say, so the only times he makes himself known is when he's bored and wants to keep me or one of my family members up. if you meant getting them to help you with stuff, i've never really asked, only time i did was when i wanted someone out of my house. my whole coven has dealt with Rori in some degree, so they know how intimidating he can get when he's upset. my one friend is amazing with pendulums so she's usually the channel when we're speaking with spirits. she doesn't hate Rori, but when it's him, she says it feels like two frozen hands are being slammed into her back. lol, sorry if it went a bit off topic, guess to make a point, it is possible to have spirits become physical and help you with stuff like kitchen faeries or something, just never tried it.
