I've ruled out my breath, but I can't be sure. 50% humidity where I am, occurs inside and outside, and AC is not a determining factor.

The smoke/mist is coming from my peripherals inwards. Unusual for breath clouds, in my experience.

It's starting to freak me out.

Any physics nuts out there have a good explanation so I can stop feeling paranoid?

Some of my recent research would definitely have made me a target... Graphics coming Soon™.

Worst-case scenario: I'm being haunted.

Best-case scenario: my narcolepsy is causing me to hallucinate.

I doubt it, but is anyone else experiencing strange phenomena?
