Not about your thread.
Your comment on how fear can hurt the mind is in many places, and it was well said in Dune.
The best example was where he put his hand into a fire box, and the presumed situation was damage, the visceral emotional feeling, but the thinking feeling knew it not true. Also Daniel story.
So that situation is can you choose with thinking to override an instinctual feeling that does not make sense.
The visceral illusion tries to create fear of future damage, from one possible perceived future, based on the damage he thinks he feels in the fire box. But he knows mentally that his hand is not being damaged.
It has the idea of thought, and thinking overcoming perceived possible futures. And most of fear is a perceived possible future, trying to direct an action.
In that you can see a twinge of temporal lore, but constructed by ones own mind of letting a perceived future define some action, something that should not be done if it does not make sense.
In temporal lore, people believe the future is messing with the Now.
When in fear, a perceived outcome in the future, messes with your choices in the Now.
The choices of the Now, should be based on best decisions, not illusions based on fear of low probability, or unknown possible futures. And most fear tries to create a low probability event, that can not be known, as what someone will think will be the future.
A person afraid of flying, has an unpurportional view of what will happen when they fly, and that wrong perceived future out of perspective controls there feeling in the now.
Also why I like this song.

Molly Hatchet: Flirtin With Disaster
http://www.youtube.com/watch?v=rhhtRxqSrysThe molly hatchet song can easily be seen as not letting some 'perceived fearful future' change what you think is best. But instead making sense of it, even if it might feel like a gamble, without that illusionary fear, you choose your destiny.

Could be a touch of the Dune fire box encounter also in that song.
