I can definitely - 100% assure anyone, that the mind, or memory is subjective.
I lived in Hollywood for three years and drove every single day on the roads there.
I grew up in the UK (we drive on the opposite side to the US.....)
Here is the really trippy bit....
If I think back at that time - in my head (and visualizing the roads) _ I am driving on the 'left'_. (not the right, as it should be)
I know this to be absolutely -100% - incorrect.
And even if I try to imagine driving on the correct side (as I did every day for 3 years) - it doesn't compute!
It was very strange coming to the realization.
It is totally empirical evidence, and not a subjective 'I think..'
