Replying to Difference between brain and mind?

SO because I have derealization I always have moments where I don't really know whats going on as if I'm always dreaming. But these moments lead me to some crazy thoughts or things I've analyzed by myself with my own logic. I really wanna see people different views on questions that are more open-ended.

 Such as is a person a person once it can logically think for itself and analyze its surroundings?


 Or is the human body just a capsule for the brain to have thoughts, logical, action and such pushed through? Could we think as ourselves if our brain was placed in a different body if there were feasible ways for a body transplant?

So is there a difference between the mind and a brain?
 I have my own answer which is, Yes there is a significant difference. A brain is just a brain when you think about it. The brain is still classified itself without the mind in part of it. But to have a mind you need something for it to be contained in. It is almost like a gas that can only be used when contained. If it were not contained there would be no purpose for it other then to just be there.

I could write endless pages on these sorts of topics but that would take too long obviously. So back to the questions I've been asking you NS, Is there a difference between the brain and mind?
