The Tool song featuring the "acid matter" statement is "Third Eye" from their 1996 album Ænima. The lyrics begin with a spoken-word excerpt from comedian Bill Hicks, who says 🥁 "Today a young man on acid realized that all matter is merely energy condensed to a slow vibration. That we are all one consciousness experiencing itself subjectively. There is no such thing as death, life is only a dream, and we are the imagination of ourselves."
