8 Things to Remember Before You See Captain America: Civil War

There's a weird scene in Avengers: Age of Ultron when Thor leaves his team of Avengers to basically take a bath in a cave. There, he has some crazy hallucinations of Asgard being destroyed while Heimdall (Idris Elba) seizes dream-Thor by the neck. He also gets a glimpse of the Infinity Stones, which will come into play later.

Once Thor helps the Avengers defeat Ultron, he takes off to figure out what his vision meant and if his home planet is in trouble. Seeing as the next Thor movie is subtitled Ragnarok and according to Marvel's president that "means essentially the end of all things," it doesn't look good.
