For those that have taken hallucinogens, the perception of time moves more slowly, the more so expanded, the more seeming so. However, while affected so, one only is aware that is the case after some time has passed and then one looks at a clock, only to be surprised to find much less time passed than what it mentally seemed. In other words, perception feels normal and not like watching a slow motion film.
If expanded so while actively participating in a sport, it is also possible to perform as though one has modestly more time to both perceive and react even though other negative effects may result in no advantage unless one has trained to overcome negative effects. Note, supposed research will tend to state the opposite that is more about publicly discouraging there are any such advantages. At the same, they will ban whatever as cheating that shows they actually know otherwise.
The same mental phenomenon can occur while sleep dreaming. While say one is sleepy while watching a tv program, one may briefly nod off, and then wake up ten minutes later (from a loud commercial), and wonder why the dream seemed to have been a much longer episode of whatever that in the dream seemed to be moving along at a normal rate?
The above indicates the perception of time passage is neural system based. Accordingly, that is likely why as we age, time awareness moment to moment doesn't seem to be moving along any faster than when we were younger while when one checks how many years have passed, it seems to be accelerating.
