Nightmares 

It’s common for your sleep to be affected when you work in policing. Nightmares can be one way your mind tries to process overwhelming experiences. You might notice that your dreams replay some events, including themes of danger or helplessness, wake you suddenly with fear, or make you reluctant to go back to sleep. During the phase of Rapid Eye Movement Sleep (REM sleep), your brain is highly active. It is in this phase where you are processing emotional memories and nightmares are your brain’s way of trying to make sense of any intense experiences. Nightmares are normal for most people, even outside policing, and they are generally harmless. But if they happen frequently, they can disrupt your sleep, which over time may affect both your physical and mental wellbeing.
