Situations like being bullied at school, getting fired from a job or losing your train of thought during an important speech can feel mortifying when they occur. But in time, and with the help of sleep, the shame and embarrassment fade away. You can recall the experience without re-experiencing the emotional charge. This may not be the case for people with insomnia, results of a new study in the journal Brain suggest. Insomnia may involve disruption of the brain’s processing of emotional experience, burdening poor sleepers with emotionally charged memories. Here’s more about it.
My insomniac nights are rare these days—but I had one last week. Nearing bedtime, it felt like a train was running through my body with the horn at full blast.

Here’s what may lie behind our trouble falling and staying asleep.
