The last thing I will do is deny anyone else’s experience but it sounds like you want to do that, all the while unaware of where that impulse originates. As if it percolated up into consciousness completely unbidden or did you will it into existence?
The self is synonymous with experience. It’s why the self is simultaneously a substantial entity and completely without substance. We remember what it felt like to be ten years old and yet every single cell that generated that sensation has long since been replaced by adulthood. People who receive traumatic brain injuries can become strangers to their family and even themselves. The self is a contrivance and an emergent property of a neural network. Ever changing, elusive and yet reassuringly familiar.
