And even if it were, Dreama would just mean "Dream" with an -a at the end. I highly doubt it means "joyous music" in Greek either, but I could be wrong.
Anyway, Dreama reminds me of how one time when I was in sixth grade, this kid wrote a poem for my friend
Gina, and one line went "All I do is dreama / About a girl named
Gina". =P
