I've been getting a thin colourless heat haze shimmer layer like that for a few months now. If I switch off my bathroom light (which dims away gradually over the course of about a second) while looking in the mirror after sunset, I usually get a burst of what I presume is the second layer - a 3 inch, very bright coloured corona lasting for the duration of the dimming, and sometimes it hangs around long enough afterwards to watch it follow body motions too. The colour is uniform so far but different on different days, fluorescent marker pen type colours of different strengths depending upon the lights levels.
