lastnight i had a very long ld, and at one point i even thought i had went crazy, and could no longer tell realety from dream. So i have about my 4th FA in the dream, and after that i began to think i had died, and tried to wake up, but still couldnt. the dream was or felt like a hour long, and was fun, and im still amazed at how easy i stayed anchored in lucidety.
wow thats crazy and amazing at the same time. it sounds like that movie “Waking Life”. i cant even manage to get lucid let alone stay lucid for hours lol
It happend to me in first LD lol
I just wanted to open my eys and wake up !!! and I succeed.
It’s all a matter of belief. If you believe you will wake up, you most certainly will. (except that waking life guy, he’s in a coma 
)
If you think you will stay in the dream, then who can deny it to you? It’s your mind’s work, after all, and your mind is ultimately the arbiter of what happens in the dream.
so how could i have that indurance in all my LDs?
With practice, like all things in the world
