Lucid dreaming seems to be becoming more common.

Science wakes up to people's increasing ability to manipulate their own dreams

I have wonder if it has anything to do with video games (ie: visual entertainment you have some control over) becoming more a part of day to day life. I guess you'd test that by finding out if people who play more video games have more lucid dreams.

I have them once in a while, and they usually end up being my more interesting and memorable dreams.
