Dreams are full of possibilities; by drifting into the world beyond our waking realities, we can visit magical lands, travel through time and interact with long-lost family and friends. The notion of communicating in real time with someone outside of our dreamscapes, however, sounds like science fiction. A new study demonstrates that, to some extent, this seeming fantasy can be made real. Scientists already knew that one-way contact is attainable. Previous studies have demonstrated that people can process external cues, such as sounds and smells, while asleep. There is also evidence that people are able to send messages in the other direction: Lucid dreamers—those who can become aware they are in a dream—can be trained to signal, using eye movements, that they are in the midst of a dream. Two-way communication, however, is more complex. It requires a person who is asleep to actually understand what they hear from the outside and think about it logically enough to generate an answer, explains Ken Paller, a cognitive neuroscientist at Northwestern University. “We believed that it was going to be possible—but until we actually demonstrated it, we weren’t sure.”
For this study, Paller and his colleagues recruited volunteers who said they remembered at least one dream per week and provided them with guidance on how to lucid dream. They were also trained to respond to simple math problems by moving their eyes back and forth—for example, the correct answer to “eight minus six,” would be moving your eyes to the left and right twice. While the participants slept, electrodes attached to their faces picked up their eye movements and electroencephalography (EEG)—a method of monitoring brain activity—kept track of what stage of sleep they were in.

In our postmodern world, studying the classics of ancient Greece and Rome can seem quaint at best, downright repressive at worst. (We are talking about works by dead white men, after all.) Do we still have things to learn from classical philosophy, drama, and poetry? Shadi Bartsch offers a vigorous affirmative to this question in two new books coming from different directions. First, she has newly translated the

Much of Cohen’s work is driven by his aversion to a type of spatial metaphor that minimises the value and variety of familiar experience. His first book, Spectacular Allegories (1998), a study of modern American fiction and journalism that emerged from his PhD, questions the postmodern idea that spectacle somehow floats “outside” history and “above” material reality. It was written before Cohen was a practitioner, or even employed Freudian theory. He told me that his “obsessional preoccupation – and I’m pointedly using the singular – has been what is concealed in what is right in front of us, in what is present”. He isn’t only talking about unconscious blind-spots. The book’s title is “filched”, as he puts it, from the American poet Wallace Stevens, and Cohen expressed a particular fondness for Stevens’s idea of a “strange presence that irradiates through the world that his poems are always gesturing towards and trying to get us to see”.
We knew that the persistent cough spelled his end. The fever had preceded it, just as it had in his mother, brother and dozens around him. The contagion that was devastating society had him in its throes. When he finally died, a postmortem showed his lungs had been decimated. He’d suffocated, drowning in his own inflammatory fluids.

In May 1803 a group of enslaved Africans from present-day Nigeria, of Ebo or Igbo descent, leaped from a single-masted ship into Dunbar Creek off St. Simons Island in Georgia. A slave agent concluded that the Africans drowned and died in an apparent mass suicide. But
The expression of frustration could have been sent from any tier in travel-restricted Britain: “Where do you go in July? For me, I cant answer. I am longing to go to London, & hoping to the last. That is all. For the present, … certainly the window has been opened twice – an inch – but my physician shakes his head or changes the conversation (which is worse) whenever London is mentioned. But if it becomes possible, I shall go – will go! Putting it off to another summer is like a never.”
