What are nightmares?
Nightmares are the bad dreams that lead to awakening from sleep. Upon awakening, the dream sequence and content can be described in detail, people remember in detail what they dreamed.

There are also cases in which the perceived threat can be more subtleinvolving failures or personal difficulties.
Nightmares after emotional traumas sometimes reproduce the situation dangerous or threatening that the individual went through, but in most situations nightmares do not replicate real facts.
People can experiment several nightmares in the course of a single night, often for the same reason. Nightmares appear almost exclusively during REM sleep, the stage of sleep that repeats during the night for approx. 4-5 times.

Nightmare or night terror?
Nightmares and terror of sleep represent distinct sleep disorders, but which have in common:
Awakenings or partial awakenings Awakenings accompanied by fear and vegetative activation.
Nightmares generally occur during REM sleep, usually late at night. These produce intense dream images, full awakenings, mild vegetative arousal and a detailed evocation of the event.
Instead, Night terrors usually occur in the early hours of the night, during stages 3 or 4 of NREM (non-REM) sleep.. Night terror produces incomplete awakenings that cause a state of confusion, disorientation and partial reactions, with a significant vegetative excitation.
Unlike the nightmare, the sleep terror is associated with amnesia about the respective event when waking up from sleep in the morning.
The majority of the adult population, regardless of age, goes through terrifying dreams at certain moments in their lives. However, nightmare disorder is a condition that requires diagnosis and treatment when the frequency and severity cause significant suffering in the patient’s life and a deterioration of personal, professional, social life, etc.
