Discussing the question, some times ago, with an old friend, she gave me her never-failing remedy for sleeplessness, which was to imagine herself performing some trivial action over and over again, until, her mind becoming disgusted with the monotony of life, sleep drew the curtain.
Is "discussing the question" an unattached participle？ I think the implied subject of it is , Instead of the subject of the sentence, the speaker.
Is that acceptable？I know the meaning is clear, though.
The famous old plan of counting sheep jumping over a stile has never served my turn. I have herded imaginary sheep until they insisted on turning themselves into white bears or blue pigs, and I defy any reasonable man to fall asleep while mustering a herd of cerulean swine.
