heavier-than-air toxic gas

Last night I was asleep, dreaming about why I couldn’t sleep. I deduced there must be a toxic, heavier-than-air gas in the area that I was sleeping. As I move around, I stir it up, sometimes inhaling it, sometimes not, sometimes mixing it with good air. I decided I was sleeping in some type of bowl and when I woke up I would have to use a fan to blow all the heavier-than-air toxic gas out of the bowl. Then I’d sleep well.

Overall, I woke up thinking I slept well. And according to my tracker, it was one of my best night’s sleep ever. Dreaming about not sleeping was just a dream

Have a wonderful day!
