This sort of thing comes up now and again, and all I can really say is: don't harm yourself by doing this incorrectly or without the proper support. If you're meditating intensively like a sesshin or a retreat, you really need some kind of experienced teacher or access to a proper community to help you deal with this kind of stuff. I am a practicing buddhist of the Zen variety, and I certainly couldn't do a 10 day vipassana retreat, even after actual years of practicing staring at a wall. People who expect to be able to do this kind of stuff, with a 'teacher' that got his/her credentials by sending off 500 dollars to deepak chopra without such things happening are misguided at best and being taken advantage of (read: suckers). There are no shortcuts, look after your health, don't overdo it. Don't pay charlatans.
