The "Poker Face" singer dreams of being a groupie who took hallucinogenic drugs and followed The Beatles around trying to get them into bed.
She said: "I'm quite sure that if it were 1968 I may not be the Lady GaGa that I am today."
"I might be arguing with Yoko Ono and trying to win John Lennon's heart and chasing The Beatles in a bus on LSD, hoping that one of them hands me a microphone one day."
The 23-year-old New Yorker – who has had two number one UK hits in 2009 – is also looking forward to the Glastonbury music festival in England in June.
She has warned fans they can expect something outrageous as she has experimented with drugs at US festivals.
She added to Britain's Daily Star newspaper: "I can't wait for the festival season, especially muddy Glastonbury."
"I love all that. I play the Lollapalooza festival in America and before anyone knew of me as an underground songwriter and pop musician I was quite frequently naked and tripping on acid in fields with my friends."
"I used to do Iron Maiden's 'Run to the Hills' in Indian headdresses and bikinis and run round the stage with hairspray on fire. It was freaking amazing."
