That's cool; I hadn't done the fist thing described in the article before, but I can make the sound independently, too.

Yup!

My weird thing is Exploding Head Syndrome. I "suffer" from both the auditory and visual incarnations, so sometimes when falling asleep, I'll either hear a very loud bang (sounds like a door being slammed to me) or see a bright flash that wakes me up.
