Not surprisingly we are left with a vague sense of unreality. Low-level stress inhibits us all the time, increasing our fear of fear. Our brains are triggered by tiny problems to commence firing and then shut down with alcohol or drugs. Of course, Stressspeak may really be throwaway . Or perhaps there is some better explanation for its use.
More rigorous research is needed, properly funded, monitored, controlled.
But one thing is certain. If my unscientific interpretation is even partly valid, we should not be managing stress, as we are commonly taught to do. Although tension is felt by most people to be unpleasant, it is none the less part of a survival process, like those other expansion contraction wonders of sex, childbirth and digestion. Very occasionally people die during these activities. But as a species we interrupt them at our peril.
