Parasomnias

 Like every field of life, sleep has it's phenomena - parasomnias. They are extremely rare, nevertheless they occur. Some are benign, others can be harmful, depending on your surroundings and your mental state. The most common ones are: sleepwalking (and its different variations), sleep terrors, sleep paralysis and exploding head syndrome.
    Sleepwalking, as the name inclines, is a phenomenon ralated to unconscious walking. This parasomnia doesn't harm its victim directly - as long as there are no objects which we can hurt ourselves with. If we know that we are vulnerable to sleepwalking its advised that we hide sharp objects, lock our doors and hide our keys. Two of more common sleepwalking variations is sleep-eating disorder and RBD. The first one makes it so that the victim eats while sleepwalking and the latter makes it so that one acts out their current dream. 
    Sleep Terrors are a variation of nightmares, though they lack the visual aspect of dreaming. Its victims usually feel dread and very strong stress whithout seeing anything before waking up. Also, they occur in a different phase of sleep. While nightmares happen during the REM phase, Sleep Terrors come about in the deep sleep state - that's probably why we don't see anything.
    Sleep paralysis is a parasomnia which involves complete inability to move your body while retaining consciousness. When we go to sleep, our brain gradually cuts off the ability to move and think so that we don't hurt ourselves during sleep. During sleep paralysis our brain cuts off the reactive parts of our muscles but leaves us conscious. Some parts of our brain get switched off and we might expierience hallucinations.
    At last one of the weirdest sleep phenomena - exploding head syndrome. Victims of this syndrome get woken up by a loud screeching noise in their head. It usually occurs in the blurry period right before falling asleep or waking up. It's yet unknown why this parasomnia happens.

    All of them sound pretty dreadful, to be honest. RBD could be quite dangerous I suppose (if you dream about flying, for instance). What does the acronym stand for?

      RBD stands for "Rapid Eye Movement Behavior Disorder"

Maladaptive daydreaming

    Scientists estimate that an average person spends around 47% of their active time daydreaming. Doing so is considered healthy, as it enables us to slow down and collect our thoughts. Some people though, may experience daydreams so intensive that they get distracted very easily. Such a condition is called Maladaptive daydreaming or daydreaming disorder. It usually gets  triggered by stimuli such as smell, noise, sound or even conversation topics. Maladaptive daydreaming can develop as a coping mechanisim in response to trauma or sustained and prolonged stress - it helps to switch off while feeling stressed out. Usually people who already suffer from other mental illnesses or disorders are prone to this condition. OCD, depression and anxiety might be the primary cause of developing maladaptive daydreaming.  https://www.sleepfoundation.org/mental-health/maladaptive-daydreaming

Sleep disorders

 Sleep disorders are conditions that influence the quality and amount of sleep that you get. Everyone can have problems falling asleep once in a while but sleep disorders tend to stretch for long periods of time. Usually as result, even though you’ve slept a healthy, recommended amount of time, you can experience weariness and fatigue. There are around 80 different types of sleep disorders but most common types are insomnia, sleep apnea, restless legs syndrome and narcolepsy. Insomnia prevents you from falling asleep, sleep apnea influences your breathing patterns while in slumber, restless legs syndrome is a type of sleep movement disorder, and narcolepsy makes you fall asleep during the day due to extreme exhaustion. Such conditions aren’t rare to find. Around 70 million people in the US suffer from such disorders. https://www.mayoclinic.org/diseases-conditions/sleep-disorders/symptoms-causes/syc-20354018

Sleep apnea

     Sleep apnea is a sleep disorder which repeatedly prevents or stops its victim from breathing. The disease cannot kill people but the complications can shorten ones lifespan. It dramatically lowers ones sleep quality and makes it almost impossible to wake up well rested.      There are three different types of sleep apnea - obstructive sleep apnea, central sleep apnea and complex sleep apnea syndrome. The first occurs when ones throat muscles relax. The second happens when our brain doesn't send proper signals to muscles that control breathing. The last one is a combination of the first two and is the most lethal.      Loud snoring, gasping for air during sleep, waking up with a dry mouth and hypersomnia are common symptoms of sleep apnea. It's very hard to find out ourselves that we have sleep apnea and round 38 thousand people die from the disorder annually. https://www.mayoclinic.org/diseases-conditions/sleep-apnea/symptoms-causes/syc-...
