the sledge hammer metaphor is hilarious. LOL
Now....to extend that metaphor a bit: imagine that you say "oh, damn! Our car is broken!" and your little toddler overhears you and knows you are very upset and feels bad for you and wishes she could help.
In trying to help (but only being a rather pathetic three-year old) she gets her trusty container of glue and walks out to the driveway. She climbs way up on Daddy's car and slowly and carefully starts squirting the white sticky awful Elmers paste down into the cracks on the hood. IN a matter of minutes, the entire engine is covered in glue. It hardens. It ain't pretty.
Off to the side, while Mommy and Daddy scream "WHAT THE FUK HAPPENED TO THE DAMN CAR NOW?!" the little toddler smiles to herself thinking "I did good. I 'fixed' Daddy's broken car..."
That's the Unconscious.
Well-meaning and very very stupid, lol...alot like a toddler with a ladder. Dangerous. Very dangerous. But not at all evil. Just "primitive" in its tools and in its thinking. To the Unconscious it makes SENSE to say "well, if he is having so much trouble being him right now, maybe if he felt like he WASN"T him anymore..." and the rest is dp history.
Peace,
