We can't name experiences (as God, demons etc) without cultural knowledge. And there's generally more than one name we could use: the 'supernatural' explanation is probably never the only possible one. So Boldylock's sister and her pastor call her experience a demonic attack; if she'd spoken to her doctor instead, I expect he'd have called it
sleep paralysis with
hypnagogic hallucinations, and reassured her that it wasn't dangerous. I'm not sure which response would be more helpful, though.
Anyway - we need knowledge to name experiences, and names to think about experiences. But do we need it in order to
have the experiences? I think not.
