Arcana Coelestia #5239
5239. 'And he interpreted our dreams for us' means what the things foreseen in obscurity held within them. This is clear from the meaning of 'interpreting' as what was held within, dealt with in 5093, 5105, 5107; and from the meaning of 'dreams' as the things foreseen in obscurity, dealt with above in 5233.
Arcana Coelestia #5105
5105. 'And there is no interpreter for it' means that no one knows what they hold within them. This is clear from the meaning of 'the interpretation' as the explanation of what something holds within it, dealt with above in 5093, and so of what those dreams held within them.
