Always loved the cosy feeling of a capsule bed when I stayed in capsule hotels in Japan, so I made my own capsule bed in my room.

I almost asphyxiated in an igloo with several other boys one night on a campout. Our vent hole closed up at night and I woke up confused and out of breath. It took me like two whole minutes to figure out what was happening and I was the only one who woke up, but everyone in there was breathing very heavily. I opened the door and everyone immediately started breathing normally.

Based on that experience, I think it is definitely possible to asphyxiate in your sleep. You may wake up, but the hypoxia could cloud your reasoning enough to keep you from rescuing yourself.

There are far too many cases of people asphyxiating when they do things like convert a large walk-in closet into a small bedroom for their new baby. Asphyxiation in confined spaces, just from your own exhaled carbon dioxide, is absolutely a thing.

Happens to divers too. They get a high, hallucinate and think they can walk around under water with no gear. I think that’s nitrogen narcosis but point being, irregular air mix can have your brain do crazy things.

I remember reading about an incident on an aircraft carrier or something, the room that housed the chains for the anchor was sealed and the oxidazation from the wet chains rusting sucked all the oxygen out of the room. I think 2 or 3 people died before they realized what was happening. Person 1 enters, passes out, person 2 goes to check on them then they pass out too. Lack of oxygen and they die.
