I heard phrases like
My brain is telling me ..., but i know ...
For example:
My brain is telling me to stay with him/her, but I know that it's not the right thing to do.
It sounds like people have a separation between their brain and something else that they think is them / something that defines as them (maybe their consciousness or soul).
I want to know if there is a name for that. I think it is similar to the "Who am I?" question.
