We have all had them: the scary dreams of being chased by an ax murderer or giving a presentation for which you're not prepared (or not wearing pants). Nightmares can be stressful as well as terrifying, and they can make you lose a lot of sleep. There are many different reasons nightmares happen. Some are very simple, like eating too much or at the wrong time, while others are complex and based on past experiences and traumas.
Worry is one of the most common causes of sleeplessness and, perhaps not surprisingly, it can also disturb sleep. Stressors and anxieties that plague you during the day can manifest themselves as dreams full of monsters, missed tests, or other stressful situations. The exact thing causing your stress could manifest in the dream, or it may take an entirely different, ominous form.
