All I see is flare from bright light sources in a low light setting, and lens flare from pinpoint sources (those circular shapes with starbursts in them). It's all exacerbated by motion blur. Kind of looks like the motion was fore/aft vs. left/right - there's almost a "zoomed" look to the screens on the sides.
I don't see a "lens that got wet because it was cold" or a dirty lens (in my experience, a dusty lens or filter gets flares from actual bits of dust, usually apparent on wider glass). The diffuse look from the hanging lamp could be from a hazy or smudged lens, but in these conditions and film, etc., I'd expect some highlights to bloom out like that.
