This is too intense. Worse than the torture of asphyxiating and equally out of his control, because this is not a memory he is retrieving of his own volition. It’s somehow being projected for him, against his will, and he thinks perhaps there’s a reason our memories are kept hazy and out of focus. Maybe their abstraction serves as an anesthetic, a buffer protecting us from the agony of time and all that it steals and erases.
