Seeing things that already happened...

[Yobz]

Maybe this should go in psychology or something, but this forum seems appropriate as well:

Let me describe the course of events, this happens all the time (probably to you as well):
1. I use my cell phone and set it down on the table
2. Backlight goes off and that catches my eye
3. I turn to look to see what the turning off of the light was and catch the tail end of the light turning off.

BUT think about this: how could I turn to see it turning off since it is the cell phone turning off that caused me to look in the first place.

This seems bizarre...
