Internal Medicine

Bad dreams, or nightmares, are commonly caused by stress, anxiety, depression, PTSD, and neurodevelopmental conditions like ADHD. They can also be triggered by sleep deprivation, certain medications, or trauma. Reducing stress, improving sleep hygiene, and seeking treatment for underlying mental health conditions can significantly reduce their frequency.

Because bad dreams can stem from many overlapping causes, identifying the specific trigger is the fastest path to relief. A free, instant, online symptom check can help you pinpoint likely causes based on your unique situation and guide you toward the right next steps—whether that's lifestyle changes or speaking with a professional.
