How much sleep do you need?

In separate studies at the University of California, researchers have found that the human brain needs a certain amount of sleep every so often to effectively "recharge" itself but that too much sleep or too little sleep seems to be associated with a shortening of your life-expectancy.

They also found that the brain needs to rest for a minimum amount of time on a regular basis. So going for several days at a time with minimal sleep and then having a lie-in is no solution.

Obviously the amount of sleep different people need varies so it would be interesting to know what your experiences are. For example, what happens to you when you get very tired? How do you feel if you have a big sleep after several short nights? Do you notice a difference in your alertness if you have been dreaming in your sleep?
