Use of the Pink Floyd lyrics are not just a reference to film context but also the film's production history.
According to Den of Geek's Mike Cecchini "Using the song 'Eclipse' in the Dune trailer is not only thematically appropriate (the film’s logo also appears to depict an eclipse, and the planet Arrakis, the titular desert planet, is orbited by two moons, which makes solar eclipses far more likely), but it’s also a nod to a previous version of the project that never got off the ground, as famed director Alejandro Jodorowsky once had hoped that Pink Floyd would score his version of the film, which was sadly never made."
