8 Strange Sleep Disorders
1. Nightmare disorder: When the occasional nightmare becomes a common problem, so you wake up in a sweat or you’re afraid to go to sleep, then you could be suffering from nightmare disorder. According to the American Sleep Association, stress and sleep deprivation are the main triggers for this disorder.
2. Sleep walking: The causes of sleep walking are not fully known – although genetics, broken sleep and stress are thought to play a role. Sleepwalkers open doors, move their furniture around, and move from room to room with no trouble at all. According to the Journal of Molecular Psychiatry, 19 percent of adult sleepwalkers have been injured while sleep walking. The main risks are tripping and falling.
3. Exploding head syndrome: This disorder occurs at the onset of deep sleep, when a loud noise awakens up someone who’s just fallen asleep. These sounds range from explosives going off inside their head, to cymbals crashing loudly, right next to their bed. Of course, there’s no actual sound – so it’s all a mystery. The person’s not at risk - and there’s no obvious cause.
4. Hypnagogic hallucinations: These occur as the person is falling sleep or at the end of the night as they start to waken up. The person’s sure they can hear voices, or they experience strange sensations, or they report seeing people or weird objects in the room. A common vision sufferers have is seeing small animals or thinking they see bugs crawling over the walls. According to the American Sleep Association, these kinds of sleep-related hallucinations are most frequently reported in people with narcolepsy.
