Really I think you're just describing awe, which as traditionally defined [0] always included (or at least, certainly did not preclude) an element of fear. This seems completely natural to me, but I grew up with a sort of old-fashioned understanding of certain English words. The use of the adjective 'awesome' in recent decades has perhaps helped people to forget its negative connotations.
