'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

5092. 'Each his dream in one night' means regarding what the outcome would be, which to them lay in obscurity. This is clear from the meaning of 'a dream' as foresight and consequent foretelling - and because a foretelling is meant, so also is the outcome, it being the outcome that is foretold; and from the meaning of 'night' as obscurity. In the spiritual sense 'night' means a state of shade brought about through falsity that is the product of evil, 1712, 2353, and so also obscurity, that is to say, mental obscurity. The obscurity belonging to night in the world is natural obscurity, but the obscurity belonging to night in the next life is spiritual obscurity. Natural obscurity comes about because the sun of the world is absent and the light received from it is lost, whereas spiritual obscurity comes about because heaven's sun, which is the Lord, is absent and the light, that is, intelligence received from it, is lost. This latter loss does not arise because the sun of heaven sets as the sun of the world does, but because a person or a spirit is living amid falsity that is the product of evil. He himself moves away from that sun and brings obscurity to himself.

[2] An idea simply of night and of the obscurity that comes with it is sufficient to enable one to see how the spiritual sense and the natural sense of something are related to each other. Furthermore there are three kinds of spiritual obscurity - the first being that which is due to falsity that is a product of evil; the second being that which is due to ignorance of the truth; and the third being the obscurity in which exterior things dwell, compared with interior ones, and so the obscurity in which ideas formed by the senses and present in the external man dwell, compared with the rational concepts present in the internal man. All three kinds of obscurity arise however because the light of heaven, or intelligence and wisdom flowing from the Lord, is not received. This light shines unceasingly, but falsity that is a product of evil either rejects, smothers, or else perverts it; ignorance of truth receives only a little; while ideas formed by the senses that are present in the external man reduce it to a dim light by making it a general or ordinary one.
