I think more people are starting to accept lucid dreaming as real. Look at how fast the forums are growing. The lucidity Institute does workshops on it. I have run into people who at least herd of it. Lucid dreaming has also been a topic on a few sitcoms and in movies. The word is getting out so, it is just a matter of time before it becomes widely accepted.
The main barrier (I believe) is that people don’t really think it is possible until they have one. I was the same way. I believed it (but, not really) until I had my first one. I think the same is true for a lot of people.
