If I'm to guess that you may referring to electron flowing from negative to positive as would be in a DC power source then the answer would be No.
With AC the negative and positive change positions with the frequency. Then, is oscillation means changing direction then the answer is yes. But remember that electrons travel at the speed if light, 186,000mp sec. So, then the question is does a single electron in a conductor actually oscillate or it it so fast that it travels the complete length of the conductor and never has a chance to reverse directions.
The thought is further complicated by adding transformers and magnetic coupling etc. from the point where the power is being generated to the actual load.
But, it may be nice to know out of curiosity but is it necessary to know?
