Wet dreams can occasionally be non-sexual, like a wet dreams about the word Legos. Sometimes the sexuality is masked, as in a dream about the Washington Monument.

Wet dream is also the name of a solo album by Richard Wright, the keyboardist (well, most of the time) from Pink Floyd. Very few lyrics, mostly gentle, almost ambient music.

wet dream: a dream with erotosexual content that ends in sexual orgasm. It occurs with greatest frequency in pubertal and adolescent boys. In some instances, the content of the dream is lost or fails to exist, and the ejaculate is the sole sign of the occurrence. When recalled, the topical content of the erotic dream reveals the content of one's idiosyncratic lovemap. See also lovemap; spermatorrhea.

A poem:

Goldfish swirling
encircled in a fog
wafting from unknown waters
whilst walking whales
mellowly meander
chairmen of the boardwalks
picking up discarded pop cans
and listening to the snoring sounds
of sleeping people dreaming
