I know this thread is now over, but my computer went down a couple of weeks ago when we were discussing this. I thought I should at least answer your question even if it is weeks later!! LOL!! :D
My chakras are not in perfect balance right now, and I am no authority on the subject, but I have studied yoga for many years, though laxed in the last few(!!). I studied under a tantric teacher who was/is very advanced, and also grew up reading and hearing about kundalini yoga and chakra experiences with a guru. Beyond that there are more stories, but I don't wish to discuss them, not because I am trying to be mysterious, it just doesn't feel right to discuss them.
I hope you are showered in blessings!!
Have a great week!
