Dialect Dreams

I was told by a high school Spanish teacher that to dream in Spanish is a sign that one is becoming fluent. Well last week I dreamt in Yorky and a couple of nights ago in an East-Texas twang. Discussing the accents of my dream characters with a professor, I was told that Yorkshire is to England as Texas is to the entire US. ... In other words my nocturnal brain is hosting a country/folk festival. Two nights later I woke myself up with my own maniacal laughter. Could I possibly be under undue stress?
