I've had a ton of skiing dreams. In fact it was a major dream sign of mine for a while. They're great fun, but I'm just an average skier in waking life.

Having vivid dreams is a matter of changing your way of being: the dreaming self mirrors the waking self. If in waking life you start consistently paying attention to your experiences, your dreaming self will soon start doing the same (there is some lag time before waking habits move into dreaming, so don't expect instant results, but the results will come if you stick with it). Since we remember best that to which we pay attention, your memories of your dreaming experiences will become much more clear and vivid over time.

Also, develop the habit of recalling your dreams as the first thing you do after waking. Over time, your SC will get the message and start delivering more and more dreaming experiences to you.
