I haven't had much luck with time distortion, other than being able to reproduce that waiting for the clock to reach 3:15 sensation I knew so well in high school.
I have never experienced time slowing down as athletes or people in acccidents and near accidents do. I have avoided accidents, but in doing so time did not slow down, rather my body simply reacted intelligently faster than my head could think.
I've noticed that in saber fencing that after a while you can clearly perceive moves that once appeared as a blur, but there is no attending sensation that time is slower, vision is simply clearer.
If anyone has any tips, please share.
