Nightmares are generally described as dreams that provoke feelings of terror, fear or shock, whereas stress dreams tend to create feelings of frustration, worry and anxiety. Remembering your dreams, waking from them feeling distressed and suffering poor quality sleep, can be common with various causes of 'bad' dreams.

According to 2015 research in rodents, traumatic stress can create changes in the neural pathways of PTSD-affected brain areas. These altered pathways can cause nightmares by how they impact memory recall and emotional response.

Sleeping laterally is the most common sleep position. Studies have found that right-side sleepers experienced more positive dreams and fewer nightmares than left-side sleepers. For people with heartburn or gastroesophageal reflux disease (GERD), doctors say the left side is best.
Since adult night terrors are so closely associated with life trauma and psychological disorders, many of those who endure this bedtime battle will often also exhibit signs of aggression, anxiety, memory loss, and inward pain that are often expressed in the form of self-mutilation.
Post-traumatic stress disorder (PTSD) affects many people, especially military veterans. Symptoms can be severe and interfere with normal life. One of those disruptive symptoms is night terrors. They cause a person to thrash and scream in terror in the middle of the night.
Nightmares and Night Terrors: Nightmares and night terrors plague a majority of people with PTSD, leading to nighttime awakenings and making it difficult to get back to sleep. The content of these vivid dreams is sometimes related to past trauma, with many PTSD sufferers reporting repetitive nightmares.
