Interesting, but George Harrison made this observation (with a little help from LSD) long ago:
Having LSD was like someone catapulting me out into space. The LSD experience was the biggest experience that I'd had up until that time...
Suddenly I looked around and everything I could see was relative to my ego, like 'that's my piece of paper' and 'that's my flannel' or 'give it to me' or 'I am'. It drove me crackers, I hated everything about my ego, it was a flash of everything false and impermanent, which I disliked. But later, I learned from it, to realise that there is somebody else in here apart from old blabbermouth. Who am 'I' became the order of the day. Anyway, that's what came out of it, I Me Mine. The truth within us has to be realised. When you realise that, everything else that you see and do and touch and smell isn't real, then you may know what reality is, and can answer the question 'Who am I?'

All through the day I me mine, I me mine, I me mine.
All through the night I me mine, I me mine, I me mine.
Now they're frightened of leaving it
Ev'ryone's weaving it,
Coming on strong all the time,
All through the day I me mine.
I-I-me-me mine,
I-I-me-me mine,
I-I-me-me mine,
I-I-me-me mine.
All I can hear I me mine, I me mine, I me mine.
Even those tears I me mine, I me mine, I me mine.
No-one's frightened of playing it
Ev'ryone's saying it,
Flowing more freely than wine,
All through Your life, I me mine.
I-I-me-me mine,
I-I-me-me mine,
I-I-me-me mine,
I-I-me-me mine.
All I can hear I me mine, I me mine, I me mine.
Even those tears I me mine, I me mine, I me mine.
No-one's frightened of playing it
Ev'ryone's saying it,
Flowing more freely than wine,
All through your life I me mine.
