Thank you paigeyemps for the advice.

In fact I didn't really pick up a technique to try and induce LD.
I'm reading people experience, tutorials, etc... but, as a total beginner it seems very complex to me !
I wouldn't even know where to start ?

Also, it appears that a given technique is really a personal matter, as I can see a lot of people adapting methods to their own experience.
So, I wonder if there is a general method to learn ?
Should I pick one and try it for a while ?
In this case, which one to choose ?

Well, all this is really incredible and I can't wait to experience LD (though I stay very zen about it lol !)
