O.K. "Bokeh" may not be an effect or technique or even recognized as legit by many fellow UHH posters. I'm not sure what it is but I'm sure having fun experimenting with my 35mm 1.8 Nikkor lens with a UV filter, for protection. The picture below was taken with this lens, no flash and subject was about 3 feet from Xmas tree. There are noticable small white dots on subject's face. Easily corrected with PS but any idea what may have caused this?
Reflections between front element of your lens and the rear surface of your filter.
Should I simply remove filter? TIA.
I would try removing the filter and reshooting as close to your original settings as possible. See if that removes the artifact. Good luck.
Its the UV filter for sure. Don't use one indoors, no purpose to it. Very little purpose outdoors other than for lens protection. I use the Nikon NC77 MC (Clear) filter for protection. Multi-coated UV when I need it, not often with digital.
The lens hood that came with your f1.8 35mm provides good protection and is fine to leave on indoors.

Bokeh is a motteling of the background you get when using very small depth of field; e.g. f1.8 on your lens. Your lens can do it but it isn't happening here.

Another vote for filter reflections, though I did once have a lens that produced spectacular internal reflections like this even without a filter.
Bokeh is merely a description of the quality of the out of focus image: the late Geoffrey Crawley described good bokeh as the preservation of shapes in out of focus areas, by which definition the out of focus areas in your picture do, indeed, exhibit good bokeh. It's when out of focus areas go nasty and scribbly and wiry that it's 'bad bokeh'.
