So I read WC journal post yesterday, and I then proceeded to go on everyone's favorite online encyclopedia and try to attempt lucidity in sleeping.
Unfortunately seeing as I'm a newbie in this attempt (WC has around 3 or more previous forum posts on dreams), I didn't get such an interesting experience as his was. But I think I was able to achieve the dream/awake state last night. What happened was, when I came to, I saw in front of me these faceless figures. I took a step forward, towards them and at that point I fell off the platform.
I fell and fell through the sky, and I was in fits and desperately wanted to stop falling. I also heard this voice saying "aaaaaaaaaaaaaaaa" in a semi-monotone, but that was probably me, falling. So what I did was, I said COME HERE! and threw a grapple rope at the platform that I fell from. But unfortunately the rope couldn't travel fast enough against the acceleration of my fall, and I failed to stop falling.
I then sought to grow some kind of parakoopa wings so I can stay afloat, but the wings I got were pathetically small and totally unhelpful. Despairing, I resigned to my fate at the bottom, as my senses got overstimulated due to the anticipation of the end of the fall. This sensory over-stimulation/excitement brought about the end of sub-reality.
ENDNOTES
I immediately realized that this dream bears some resemblance to WC's favourite cartoon, although I didn't really know why or how. I also discovered that over-stimulation/excitement of the senses can easily bring a person out of sub-reality. What I want to say now is: everyone, try this for yourself. It is...gnarly, and we all are excited to hear about your experiences as well on this.
