I'm an inept, but I will say the best luck I've had is upon falling back asleep after waking up. The rest of the times are failed attempts at lucid dreaming where upon realization I am dreaming the entire thing turns hostile on me and i get 'kicked out' of the dream but not always awoken.
In either case I usually get stuck in my body. Usually my head but sometimes the whole thing. Sometimes I will be able to feel the rest of my body floating up like a balloon or like I'm underwater, but usually if I try to move my head it just warps me back into where I started from. It's a very tight uncomfortable and restricting feeling, It is as I would imagine being under lots of pressure.
Unless I can get manage to get free I will wake up, the only time I was able to get free on my own was when whatever usually holds me there didn't but movement was unnatural slow and exhausting like being underwater.
