since I have floaters I monitor my vision a lot.
can you help me telling me if what im going to describe you is normal or not?

Any beam of light(a lamp one f.example) reflected in a white and smooth surface, as for example a plate, the wash-basin, or the auto body of a car, let me see like a kind of black trail. is a normal thing?

for example, a beam of light reflect into my white plate. I can see the light in the plate and when I move my eyes to the left I can see(for 1 second)like a black trail coming off from the light.

I hope you can help me, thx!! :)
