What happens when you die only you will ever know — because once it happens, there is usually no coming back and telling anyone about it. For the very rare occasions in which someone technically dies and is resuscitated, their stories can be otherworldly: those who've seen the so-called "other side" report golden tunnels of light, encounters with angelic beings, echoing voices and even the appearance of deceased relatives. These reports intrigue scientists because they are common across multiple cultures, regardless of religious background; but given their nature, they aren't easy to study. To do so, you would have to record someone's brain waves right as they were about to die, and be ready for that moment.
Which is exactly what researchers did in a new study.
