Totally possible. Try thinking back to when this site was founded. Before Alex (he's still in charge right? Haven't been here in awhile), before a lot of people. It was tiny. Right now we have 280 users online, with the most ever being 1,110. And that wasn't even a year ago. One thousand, one hundred and ten people, learning and talking about lucid dreams at the same point and time. And, that's just on this site. Not only that, but there is a total of 34,731. Granted, in the scheme of things, 30 thousand isn't absolute huge, but you can't deny that it's big. As more awareness spreads that number will only grow bigger and bigger. Sure, 30,000 doesn't mean mainstream, but you can't deny that it's something, right?
