You have to go way back to see the first time I ever drew Dream Girl. I was inspired by her KO scene in Legion of Super-heroes #9-10 (2011). I tried to draw Dream Girl getting sleep gassed by one of the alien monsters; the result was...meh. I happily jumped on the chance to give this piece a proper redraw!
Once again Dream Girl is in dreamland, this time at the hands of Emerald Empress. Her teammate Saturn Girl was already knocked out earlier, and Dream Girl is ambushed while trying to rescue her. The Empress takes out a tank of sleeping gas and uses it to keep Dream Girl subdued.
