What Part of Dreams, exactly?

     There's plenty of scientific information on dream, and that can all take up a paragraph or two easily. But I'm more interested in the sociological and symbolic side of dreams; what they mean across cultures. When googling "dreams" or looking them up in a database almost strictly scientific theory comes up, along with dozens of possibilities about why we dream. I still found a few sources for the more abstract side of dreaming.                                                                                   https://www.newyorker.com/magazine/2019/03/04/the-psychiatrist-who-believed-people-could-tell-the-future is an article about a modern man of science who believed that dreams could be premonitions of the future (thanks professor!).                                                            https://link.springer.com/article/10.1007/s41782-017-0012-y is an excellent paper I found specifically about dreaming in Judiasm from a kabbalistic perspective. Jewish culture has many different explanations for dreams, dream interpretation, as well as biblical references to figures in the Old Testament who had dreams from G-d.                                                                                                    
https://www.jstor.org/stable/1185248?seq=1#metadata_info_tab_contents is an article about how Native Americans relate to dreams. Interestingly, the cultural dream articles still includes dream theory from scientists such as Freud, which means I'll likely need to incorporate much of Freud's information on dreaming. However, I never would have found the articles without keywords such as "culture" and "religion" along with "dream theory."
