“What’s it like getting choked in your sleep?”

Here is an artwork based on the theme of “nightmares.” Apnea is basically when someone has trouble breathing during their sleep. The tentacles represent what apnea is, as it can feel like something or someone is preventing you from breathing.

Wiki: Apnea is the cessation of breathing. During apnea, there is no movement of the muscles of inhalation, and the volume of the lungs initially remains unchanged. Depending on how blocked the airways are, there may or may not be a flow of gas between the lungs and the environment; gas exchange within the lungs and cellular respiration is not affected.
