I have no ideas for Sirius and Hermione, but I have the feeling that Draco might see his father.
And Snape...maybe he sees himself?
Those are such good ideas! I buy them.
As for Sirius and Hermione, yeah they're hard. Maybe it's nothing quite so deep and Sirius is scared of something silly, like Ron being scared of spiders

Or maybe something to do with his sentence in Azkaban- maybe dementores like Harry.
I have no idea about Hermione

though I like to think she runs deeper than just school work. Maybe it's something really unexpected...
