The Complexity (and Duplicity) of the Mind

I had another dream and it illustrates the mind’s complexity and its duplicity. My dream was that, for some unaccountable reason, I was trying to repair a laser beam and it caused me a nasty injury in my eye. I woke up to find my eye irritated by the pillow it was lying on. But why did the brain create such a complicated and wrong story to explain something that was wrong?

Do our brains and thoughts always delude us?

Is belief in God a complex delusion?

Todays reading struck me in this context

Everybody who believes has eternal life.
(John 6:44-51)
