Almost succeeded at DEILD

Alright. So last night I was dreaming, and suddenly I became aware that I was dreaming. But after becoming lucid, the dream quickly faded and I woke up. I remembered not to move my body. Being pissed off at myself that I woke up as soon as I became lucid, I tried as hard as I could to imagine myself back into that dream, hoping that the DEILD attempt would work. Suddenly I feel a cool rush flow through my body from head to toe. The next thing I know it sounds and feels to a degree, what only can be best described as, my body being accelerated to the speed of light within three seconds. Being unprepared for this, I think "WOAH, damn, I think that was SP." I was now zooming in on infinity, literally. What I was seeing was constantly zooming in on the same spot, looking like the same pattern. Confused as to whether I was completely asleep or not, I think to myself, maybe I should try and pop myself in a dream. I try that, but I don't succeed. I think, well maybe if I just get out of my bed and do a RC, I'll be dreaming. After waiting for ten seconds or so, I got up, did an RC, and noticed I was truly awake.

I've got to be close. There's no doubt in my mind that it was SP that took over me. It seriously sounded like I was in a spaceship being accelerated insanely fast, and afterward I was cruising at the speed of light. Should I have waited for a second wave of SP? Should I have just continued to lie down and imagine myself popping into a dream?

Thanks for all the comments / help! :)
