Thanks for the reply MadMonkey, that's interesting about the Basketballers. The reason I started this topic was because I had just watched a Documentary on Dreams. (It was on the Special Features disc for Inception)

In the doco one of the researchers talked about an experiment that was conducted where as a group of participants were given a task to attempt to flip a coin into a cup. This task was meet with little success and the participants only managed to land the coin in the cup a few times. After this the participants were told to practice the coin flipping in their lucid dreams. When they re-tried the task in waking life after the lucid dreaming practice they had an improvement of almost double the amount of landed coins.

The doco didn't go in to much detail about the trial and I was wondering if anyone had heard of or experienced anything similar??
