The article presents a translation of Johannes Kepler's posthumous text entitled Somnium, which was published in 1634. Although it was originally published as a treatise on lunar astronomy, the format of the text also allows it to be classified as a forerunner of modern science fiction. Also, some pedagogical activities are suggested, suitable for basic education, which could be developed from the manuscript.
