Why Don’t We Dream About Our Smartphones?

Excerpt from this article:

[This theory] basically suggests that the reason why we dream is that dreams allow us to work through our anxieties and our fears in a more low-risk environment, so we’re able to practice for stressful events,” says Robb. This hypothesis also posits that because our dreams are an evolved defense mechanism, we tend to dream more often about fears and concerns that were relevant to our ancestors — so, less about, say, hacking, and more about running from wild animals. “People tend not to dream quite as much about reading and writing, which are more recent developments in human history, and more about survival related things, like fighting, even if that has nothing to do with who you are in real life,” says Robb.
