Editing Exploding head syndrome (section)

== Signs and symptoms ==
Individuals with exploding head syndrome hear or experience loud imagined noises as they are falling asleep or are waking up, have a strong, often frightened emotional reaction to the sound, and do not report significant pain; around 10% of people also experience visual disturbances like perceiving visual static, lightning, or flashes of light.  Some people may also experience heat, strange feelings in their torso, or a feeling of electrical tingling that ascends to the head before the auditory hallucinations occur.<ref name=Shar2014/>  With the heightened arousal, people experience distress, confusion, [[myoclonic jerk]]s, [[tachycardia]], sweating, and a feeling that they have stopped breathing and need to make a conscious effort to breathe again.<ref name="Cep2014" /><ref>{{Cite book|title = A Dictionary of Hallucinations|url = https://books.google.com/books?id=KJtQptBcZloC&q=auditory%2520sleep%2520starts.%2520definition&pg=PA48|publisher = Springer Science & Business Media|date = 2009-12-08|isbn = 9781441912237|first = Jan Dirk|last = Blom}}</ref><ref>{{Cite book|title = A-Z of Neurological Practice: A Guide to Clinical Neurology|url = https://books.google.com/books?id=94wgLsDk2TUC&q=exploding%2520head%2520syndrome&pg=PA248|publisher = Springer Science & Business Media|date = 2011-01-19|isbn = 9781848829947|first1 = Andrew J.|last1 = Larner|first2 = Alasdair J.|last2 = Coles|first3 = Neil J.|last3 = Scolding|first4 = Roger A.|last4 = Barker}}</ref><ref name=":1">{{Cite journal|last=Sharpless|first=Brian A|date=2017-04-06|title=Characteristic symptoms and associated features of exploding head syndrome in undergraduates|journal=Cephalalgia|volume=38|issue=3|pages=595–599|language=en|doi=10.1177/0333102417702128|pmid=28385085|s2cid=4033153}}</ref>

The pattern of the auditory hallucinations is variable. Some people report having a total of two or four attacks followed by a prolonged or total remission, having attacks over the course of a few weeks or months before the attacks spontaneously disappear, or the attacks may even recur irregularly every few days, weeks, or months for much of a lifetime.<ref name=Shar2014/>
