Strange Sleeping Experiences

Sleep apnea

How it feels: Sleep apnea is a sudden stop of breathing in a dream. The person wakes up as a result. The quality of sleep decreases, the brain experiences oxygen starvation, and it becomes difficult to get enough sleep. Arterial pressure also fluctuates during an attack, which may cause heart problems.

Why it happens: During sleep, the pharynx muscles relax, which sometimes leads to blockage of the airways. Obesity, smoking, and old age increase the risk. Fun fact in a world of anxiety: one may alleviate it by playing the didgeridoo, an Australian wind instrument.
