MY thoughts

No DID and the Id, Ego and superego are completely different.

the Id, Ego and Superego are the natural pasts of the human mind.

one (superego) being where we think about things in a logical and morals (ie knowing right from wrong, being able to think about how things relate to each other, being able to understand reasoning ie we put milk in the fridge because it will spoil, heat rises cold sinks, smoke rises clean air sinks and remains close to the ground during a fire.)

the ego is the way we organize things (ie alphabetizing books from A-Z, paper items go in one recycling box and cans go in another, plates belong with plates cups belong with cups, items that are square belong in the square group, items that are round belong int he circular grouping)

Id is our natural instincts.. kind of like salmon have a natural instinct to swim upstream to where they were born, so that they can spawn the next generation. humans have their own natural instincts that come from personal expereinces, their roles in life and their environment. Example some mothers mothers instinctively know what their children need or when their children are into something that they shouldnt be without their children verbalizing or giving any other indication. some mothers call their mothering instincts "I have eyes in the back of my head" type feelings.

The Id, Ego and superego dont take control of us,

we are able to control our behaviors ie the Superego doesnt think ok Im in control now Im going to go eat ice cream for breakfast and fly to paris today. go buy a ticket and off to paris the superego goes.

where as with DID alternate personalities take complete control and take on living as if they are a whole separate identity.. Tony flew to paris for a vacation, ate pizza for breakfast and had her own friends, bank account, clothing, apartment and job. all outside of my awareness and control.
