Gaston Bachelard said this quote

Childhood is a human water, a water which comes out of the shadows. This childhood in the mists and glimmers, this life in the slowness of limbo gives us a certain layer of births. What a lot of beings we have begun! What a lot of lost springs which have nevertheless, flowed! Reverie toward our past then, reverie looking for childhood seems to bring back lives which which have never taken place, lives which have been imagined. Reverie is a mnemonics of the imagination. In reverie we re-enter into contact with possibilities which destitute has not been able to make use of.
