Man creates his own reality by the basis of his own beliefs.
If you believe something, then it’s true in your own reality. If you don’t, then it’s not. Nothing is or is not. Life in and of itself is but a dream.
People who belive in an after life, will have one, because they truly do believe and expect it. People who don’t, won’t have one and will stop existing right after death, just like they so believe. There is no one truth to our existence.
Make life what you want it to be, just as all of us on these forums make our dreams what we want them to be. After all, life is but a dream.
I think that if LDing became “easy”, with the help of technology, people would take it for granted. It’s like daydreaming - it’s easy and free, but it doesn’t resemble reality enough to actually change anything.
Even if you do things in your dream, it’s still a dream, lucid or not. It could be efficient in some cases, if you have a short-term want of some kind, like going to a club or something. You could go into your dream and go to a club, party, and wake up with no “side-effects” like hangovers or conflicts with friends, etc. But in the long term, it wouldn’t change anything. People would start taking LDing for granted, just like most people take their normal dreams for granted.
And if people try something in their LD’s that they wouldn’t do in waking life, maybe they’ll be inspired to do it IRL too. It could be a good thing of course, but it could also be a bad thing. Human beings aren’t all good, and I’m sure some people would find a way to use LDing for negative causes.
Going back on topic (it wasn’t initially a topic about a possibly imaginable LD’ing technology in the far future but mainly Sonic922 asking what effect it could have if he spreads LD’ing today amongst friends), I don’t think it will change anything. This forum exists for ten years and LD’ing is still quite unknown. It’s almost absolutely unknown in France (though it seems there will be a movie about it soon! )
The two disadvantages you point out are very unlikely. It’s impossible to confuse real life and dreams (unless you’re crazy ). I don’t think that experienced LD’ers spend their life sleeping. It requires effort to have LD’s and lazy people are not good at it.
Thus I don’t think there will be any advantages or disadvantages in spreading LD’ing (if possible). Now I would give you the advice of choosing well the friends you will speak to. Many LD’ers complained that they have been called crazy by their friends once they told them about LD’ing. Now it’s possible to speak on forums, cause people don’t really know you and there are often many natural LD’ers who practice LD’ing without even knowing it (“o? realizing you’re dreaming is called lucid dreaming? I am doing this all the time…”)
It’s called “The Science of sleep”. It’s a comedy. It seems to be rather curious. I don’t know if it will be a good movie (neither if it will appear in America cause there are only actors who are known in France, it’s seems to be heavy-handed french humour and the special effects are absolutely ridiculous ). Yet if it’s a good idea, US movie makers probably will do a remake.
Lucid dreaming has as much to do with religion and spirituality as the dreamer themself believes. Therefore, this argument is really irrelevant, (religion tends to do this).
However, the entire idea of lucid dreaming and dreaming in general is mind-boggling. Who could imagine the concept that while someone is sleeping, they have a personal dimension that is completely owned and domainated by themself? It’s basically another level of life unimaginable to everyone but the creator itself.
Who honestly cares about lucid dreaming losing credibility? People will always have doubts, they will always be close minded. If a simple reference to spirituality in relation to a lucid experience damages lucid dreaming’s credibility, let it. The believers will still believe, it would just scare off the pessimistic skeptics. And nobody cares about them

Hopefully it will be worth seeing. I’ll get my hands on it somehow to see if it is.
