Have you noticed that, if you are under stress, you have more vivid dreams? Work stress is thought to contribute to nightmares about killing the boss. Stress at work is contributing to a regular nightmare for one in two adults (Womack, 2003). Research in the UK found that 51 per cent of respondents suffered work-related nightmares at least once a week, with the figure rising to 61 per cent among Londoners. A row with the boss was the most common dream, followed by arriving late for a meeting. Worryingly, 7 per cent confessed to dreams in which they wanted to murder the boss.
