There is some literature online about how to prevent the waking up effect when one becomes giddy/excited about the fact that they are lucid dreaming and can control it. One of these methods is "dream spinning": You spin around like a kid trying to get dizzy and then, in theory, you will be transformed to a new dream sequence without waking up (hopefully retaining the aspect of lucidity).
So last night when I was dreaming, it just so happened that I realized that I was dreaming, and, as usual, the surrounding started to fade away as I felt like I was going to wake up. So I'm like "dream spin!" And I imagine myself spinning. It doesn't do anything for the first couple of seconds. I think, maybe I should outstretch my arms to my sides, to increase the feeling of spinning that I'm feeling and BAM WHOA, it was so intense that I felt genuinely nauseous, and indeed the spinning "worked" in that it seemed to spin me into an alarmingly deep level of sleep, like in inception, only that unlike in inception, whenever I get to this layer of consciousness I feel like my heart is going beserk and spazzing anywhere between 0.5 to 5 beats per second! I tried to rub my hands (another method of sleep retention) but my hands were pinned/glued to my sides and I couldn't even bring them together! So obviously I didn't want to stay in this state (in case I die from heart attack), and didn't want to risk spinning myself even deeper into oblivion -- so I had no choice but to wake up.
Next time, I will try the hand-rubbing method without doing the spinning method. Supposedly it works just as well as the spinning, except instead of changing scenes, it will retain that scene/plot.
Then again, maybe I should just try dream spinning even more and even harder. Maybe I have to pass the stage of nausea and heart-rate confusion in order to move on to the next dream sequence...
