This has been asked before and I'm pretty sure they actually "mount" a man "IRL" while he's asleep, but simply use the dream to get him aroused without making actual social contact, which they dread.

Though as Party said below, if you can catch one and assure her, and she stops being scared of you, she'd probably be willing to have sex while awake.
