Arcana Coelestia #5235
5235. 'We dreamed each according to the interpretation of his own dream' means what was to be the outcome of both. This is clear from the meaning of 'interpretation' as what it held within it and what was to take place, dealt with in 5093, 5105, 5107, 5141, and so what the outcome was to be - [evident] from what was foreseen, meant by 'a dream', 5233.
Arcana Coelestia #5107
5107. 'Do not interpretations belong to God?' means that the Divine is within them. This is clear from the meaning of 'the interpretation', when used in reference to dreams, as that which these hold within them, as just above in 5105 - that which is Divine being meant by 'God'.
