Spontaneous Combustion

I don't really like the color change of the emote. Any suggestion to make the transition more natural?
And I'm open to every other suggestion as well.

Inspired from a nightmare I had in the night of last Friday.

There was that ugly girl the from ISP who came in for no reason. I noticed there was smoke coming from her pants, so I said "umm, your clothes are on fire."
She undressed (she looked like she was mummified), and the clothes were undamaged— then I understood that she was the torch, not the clothes. I threw water at her and she SCREAMED THE HELL OUT OF ME.
I then woke up.

I didn't have any nightmare worth waking me up at 4:50 AM since like 6 years (or waking me up at all, for that matter). I spent the rest of my sleep time doing weird dreams, like my operating systems professor triggering the alarm for fun, sending neurotoxic gas in the classroom, and letting us escape one by one. Then I complained to the department. The school actually looked more like a space ship than a school, though.
I never died in a dream.
