Dream a little dream...

Had a dream the other night, and I'm pretty sure that I need to attempt  story there...just don't know how. Here's the story idea;

Main character is a succubus. She has a sister, a brother, two parents. In the beginning she's nearly caught with another succubus sucking the souls out of two boys. She runs back to her family who puts her into hiding until it all blows over. She gets antsy and sneaks out, meets another succubus and her son who she helps get to an alternate universe, but then she goes back to find her sister...

That's all I've got. I don't know if I actually want to do that story, but that was essentially the dream.
