But not before you have reached a rather high level of technique. Before that, it feels like a sustained fight against drowning that fills your entire attention like few other things do. I'd say the threshold to mentally let go is lower in almost every other sport. That state of a background task that keeps the kind from dozing off, it's leaving plenty of attention to the mind wandering? I rarely hear that mentioned by swimmers, the state of mind trope frequently occurring is "counting tiles", which rather sounds like as if even those with perfect technique and routine don't disconnect mind from physical activity all that much.
