Twelve Dreams of Dr. Sardonicus is the fourth album by the American rock band Spirit.

However, it sold well as a catalog item and became the band's only album to ultimately attain a RIAA gold certification in the U.S., achieving that status in 1976.

[6] "Nature's Way" became one of Spirit's signature songs, but was not a big hit at the time, peaking at #111 on the Billboard pop charts in 1971.

[7] Despite these commercial limitations, Twelve Dreams of Dr. Sardonicus enjoyed significant airing on college FM radio.

A 2022 two-CD release by Cherry Red Records also included several bonus tracks and a 1970 performance at the Fillmore West.
