I've been having this issue throughout every single one of my lucid dreams but one. The problem is pretty self-explanatory, I trigger lucidity in a dream but it immediately ends within 1 to 2 seconds. After that I spend a little while in what I can explain as a state between wakefulness and sleep. During this short transition I experience a series of uncomfortable vibrations or whatever and then I wake up. I don't know if this last bit of information is relevant or not to my question but felt I should include it anyway.

I know the purpose is to stabilize once lucid, but I find the time I have to work with very limited that, by the time I fathom the idea of stabilizing I've already lost the dream entirely. I've only attempted using my senses to ground myself in the dreamworld but, I end up looking at a blank canvas at which point I realize I've fallen into this transitional stage. I've been thinking about imagining something, anything from within this limbo of a state to create myself a new dream, or even using the traditional stabilizing techniques (palm rubbing, spinning...), see what happens.

Do any of you have an idea as to what else I could do to surpass this obstacle?
