Desperate for sleep, you go to a sleep clinic, where your head is fitted with electrodes to record your brain waves...Yet according to the test polysomnography, you slept all night... Scientists have been mismeasuring sleep in cases of subjective insomnia for decades, with advanced measurements revealing different brain activity in sufferers.
