Time Perception

In some circumstances do we alter time in order to accommodate how much information our brains can store? When under extreme stress or extreme fear time can sometimes appear to slow down, at the time of the event(s) and when recalled. If during these situations we automatically record more detailed long-term memories than usual, the amount of information could be too overwhelming to process, save and still record time at a normal rate, too. It might need to be stored in an artificially stretched time scale in order to fit it all in. The information is there, but distorted in time—it's just too much information to do it any other way. Airline delays might be a close analogy—time is extended when there are too many planes to fit in the available system.
