Ah, The Fountain of Lamneth. The idea that this song is about a person's life cycle is interesting. Still, anyone with familiarity with LSD will attest that this song has a psychedelic interpretation. "(eyes) are open very wide" refers to the large pupils of an LSD taker. The "no one at the bridge" part tells of the horrors of a bad trip. "Panacea" relates the blessing of a good trip. "Have I left my life behind" refers to the feeling during a trip that the tripper has "died" and been resurrected. The beginning and end parts pertain to the "I AM THAT I AM" god-definition of "yahweh", a solipsistic experience of godhood that psychedelic-takers and religious mystics have. There is zero chance that this song has no psychedelic connotations.
