Transforming into the Sun
Interpreters explain that one who dreams of transforming into the sun may attain great kingship commensurate with the sun's radiance. One who sees a sun suspended by a chain may assume a governorship and rule justly. Sitting in the sun for treatment may indicate receiving a blessing from a ruler.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
