Thanks LLucido, it is a little extreme but you did say for all the desperate ones. Not sure how easy it would be to apply for everyone, it may fall into the to hard basket. But can see by activating a sort of fight or "flight" response would focus and lock attention in the mind and if that fear or unease lingered unresolved and is arousing enough to that person's mind it should be dreamed to release resources in the neocortex.
If anchored well with RC's it's possible but seems more of a hard trick than an easy one to me personally but would never say it couldn't work if you got the mix right.
