Heads Up - Part 2: "Headache"

Part 2 of the series I'm starting to call "Heads Up".
Hello again, I've decided to return to my world.
It still looks the same, however something odd has been going around.
Recently, I've seen a shade of green fog lurking around. It stays in my view for a small bit until it drifts away. I'm really not sure what to think of it. If I follow this green fog, it disappears as soon as it reaches a mob, be it a pig, cow, zombie, and so on. The strange thing is that it passes right through skeletons.
It took me a good half hour to realize-this fog is the same shade of green from the weird gunk that was splattering out of the mobs the other day! So what is this thing? A disease? A ghost of some sort? Whatever it is, it's airborne. To avoid getting my head blown up, I stopped following it altogether.
It's been a few days now, and I've started to see this fog a lot more. And I mean A LOT. It's like dust almost, just blowing around.
Suddenly, something started to happen. Trees started to rustle, things started to move in the wind.
The fog was back, it was moving in the wind quick. Suddenly, I started to see almost a WALL of it coming over. It was like a STORM! I ran to my house, but instantly being slowed by the massive wind and being blinded from the massive amounts of green smog around me.
It eventually cleared. But when it did, I found myself lost. I was out in the middle of nowhere, with no clear on where I was. I looked around, completely nothing. I started to get worried.
That feel of being worried got a whole lot worse...
...I feel like I have a splitting headache...
Part 3 coming soon: "Headcracker".
