What a fascinating and easy-to-digest book on the latest science around dreaming! At first, I wasn't sure what Carney would add around a topic that's been written about since the time of Freud (and earlier). But I found that having a journalist be a guide into the latest sleep science was an advantage. Carney treats the topic of dreaming as an investigation, and he lets us come along that journey of discovery with him. Rather than use the dense language you see in academic journals, Carney is great at translating the work of the researchers he talks to using relatable metaphors—and he goes a step beyond the current science by sharing the implications. For instance, I had no idea that some researchers are looking into ways to potentially "induce" or influence our dreams by matching audio cues with brain waves. (Spoiler: this hasn't been perfected yet, but Carney suspects dream hacking is on the horizon). The book also takes a historical and cross-cultural look at dreams, naps, and lucid-dreaming, and how they've influenced such figures as Salvador Dali and Thomas Edison, and factored into a tradition from India that I had no idea about called Yoga Nidra. At only about 90 pages, I breezed through "Dream" in only two sittings. Despite the quick read, it's given me a lot to think about. Maybe I'll dream about it, too.
