Strawberry Field was the name of a Salvation Army children's home near John Lennon's childhood home in Woolton.
With his childhood friends Pete Shotton and Ivan Vaughan, Lennon would roam the grounds of Strawberry Field. Additionally, each summer there would be a garden party held in the grounds, which he especially looked forward to.
Through the lens of LSD, however, the song turned from simple nostalgia into inward reflection. Lennon's self doubt came to the fore, at times clouded by inarticulacy and hallucinogenic sensations.
He later described Strawberry Fields Forever, along with Help!, as "one of the few true songs I ever wrote... They were the ones I really wrote from experience and not projecting myself into a situation and writing a nice story about it."
