Dreams about Star Trek?

I often dream that I'm aboard the original Enterprise, on an important mission. Can't remember much, except that Spock is my best buddy. He holds up a test tube to Kirk, to explain something that's happening out in space. I observer and help him with this. Uhuru and Yeoman Rand are on the bridge, but not Sulu or Chekov. And this is long BEFORE the new movie! What do you think these PLEASANT dreams might mean?
