Last night I observed U Gem "flickering". It changed magnitudes wildly
between 13.3 and 13.9 in a matter of seconds. All other stars in the field
were steady, it was a very fine night. This is the second time I recall
seeing this phenomenon.

What is the most plausible explanation for such variation in this short time
scale?

Is this in any way related to an imminent outburst?
