Stjörnu-Odda draumr (Star-Oddi's Dream) is a þáttr (short Old Norse-Icelandic tale) which recounts the dream-vision of Oddi Helgason, a twelfth-century Icelandic farmer and astronomer.
It is considered to be "a literary tour de force and altogether unique in the saga corpus" because of its saga-within-a-dream narrative.
Oddi himself thought he was this man Dagfinn, whereas the guest – the man who was telling the saga – is now out of our saga and out of the dream; and then Oddi thought that he himself could see and perceive everything which came afterwards in the dream.
So after this point the dream is to be told just as it seemed to appear to Oddi himself: he thought he was Dagfinn, and that he was getting ready for his journey with Geirvid the king.
[4]The saga is preserved in the manuscript AM 555h 4to, copied by Árni Magnússson in 1686 from the now lost late fourteenth-century codex Vatnshyrna.
