Here's two examples that come to mind:
1) Almost a year ago I was sitting on my front porch re-reading Lucid Dreaming and saw a little boy walk down the road and in front of the post office. Something about him seemed strange and dream-like. I saw him walking without paying any attention to where he was going. He continued on and went to the little convenient store.
I thought to myself, "If this was a dream that kid would have probably gotten hit by a car." I read a few more pages then glanced up to see the boy on the ground partially underneath a pickup truck that had backed out of the post office parking lot and run him over. Next thing I know, a police is there. Then the boy's Mom pulls up. The stranger is hugging the little boy.
Then - as quickly as it began - everything cleared out like nothing ever happened

I probably did 25 RCs in that three-five minute time span. But it was like I blinked and the commotion appeared then I blinked and it all disappeared. I somehow missed the intermediate stages completely.
2) The day I was invited to join MM (and about an hour after I signed up) I walked out of the shop to be confronted by the biggest, boldest, most clear in-your-face rainbow I've ever seen. A double rainbow at that. I stood there in awe and RC'd a number of times. Then I continued to do so for another half hour as I drove across town to run some errands.
