According to HuffPost, certain types of dreams may indicate underlying issues with your health. Nightmares can be caused by illness and fever, while stress and anxiety tend to lead to people dreaming about not meeting deadlines, missing an airplane, or even being hit by a tidal wave. Pregnant women may also experience dreams that are unusual, or even scary at various points during their term, while nightmares can be caused by changes in blood sugar. Likewise, mental health issues such as bipolar disorder are also regularly linked to unsettling dreams.
Bustle notes that if you often remember your dreams, it may be caused by waking or stirring regularly at night. In contrast, being unable to recall them could be a side effect of sleep apnea, which "tends to be worse during R.E.M. sleep (the stage in which we have the most vivid dreams), so this stage of sleep becomes very disrupted with frequent awakenings, thereby preventing dreaming," as Mattress Firm sleep expert Dr. Sujay Kansagra explained.
Further, dreaming of natural disasters and events such as storms may be a sign that you're holding on to some sort of anger or rage in your life, per Dream Glossary. Losing control is also a common theme among those who dream about storms.
