I suppose my underlying question here is whether it has occurred to anyone that the experiences detailed by many of these women were actually experiences of sexual assault and trauma? Often these women don't identify Satan directly but talk about other supernatural or folkloric beings lying with them against their wills, and perhaps I'm reading too much into it or being anachronistic or ahistorical, but is it possible that these women had no other means of expressing or coping with what had happened to them other than ascribing the action to a supernatural being or Satan?
Diana Purkiss discusses witchcraft confessions as potential manifestations of sexual trauma in a Scottish case in "Sounds of Silence: Fairies and Incest in Scottish Witchcraft Cases," in Languages of Witchcraft: Narrative, Ideology, and Meaning in Early Modern Culture, ed. Stuart Clark (MacMillan Press, 2001). You might also want to look at Lyndal Roper's work, and possibly Emma Wilby in a Scottish context. That being said, it is important not to view witchcraft cases solely from a mental health/medical diagnosis perspective, as doing so tends to delegitimize people's past experiences and to prioritize our modern 'belief' (eg. that witchcraft and magic isn't real) at the expense of past cultural ideology. For more on this, see the rest of the work in Languages of Witchcraft, esp. Stuart Clark's introduction and Katharine Hodgkin's contribution.
