Stars Are Souls

A very common superstition in some primitive cultures that has somehow creep into media: that when someone dies, their spirit becomes a star. Quite popular for its romantic imagery of stars and as an easy explanation of "where people goes after they die" Related of sorts with the Fluffy Cloud Heaven imagery as the to-go place where people after their death, only here is taken more literally (as in noa sky-located heaven, but as the actual sky)  and with less religious complications.

Hilariously, some cultures believe that falling stars are souls from the sky coming to earth.

Anime and Manga

 * The final scene of Sailor Moon has Usagi placing her hand over her heart and saying a star was just born (her daughter conceived).
 * Darker than Black has Earth bubbled in the new sky, where stars correspond to living Contractors, reflect their use of powers and movement (though it's not precise or quite real-time), and "fall" when the respective Contractor dies. Thus the observatories have great practical importance and are on quick-dial of local security services. In that people in power like to at very least be notified when a notoriously unhinged Person of Mass Destruction arrives into their country, and of course try to control the situation much more than this.

Film -- Animated

 * In The Lion King, Simba says he was taught that the stars are the spirits of the old kings, which gets a confirmation when he later recieves a starry vision of his father. Timon, on the other hand, claims that stars are fireflies that got stuck in the sky. That also got confirmed...by The Princess and the Frog.
 * In The Princess and the Frog, when Ray dies, he becomes a star like Evangeline, who may or may not also be an example of this.
