Yelling

I've used vocal commands to help control the dream and throw fireballs. I just start low and quickly raise the volume of my voice.

"Arrggghhh"

Is there a limit on how loud I can yell or what? How does that work?

I'll have to try it sometime.

I woke myself up yelling in a dream once. When I use voice commands normally I don't yell at all.

A limit? Doubt it. When I get excited, I start shouting and yelling so loud while lucid that I wonder if others outside my head and my bedroom can hear me. Luckily they never do, but I've never found a limit to how loud I can get, so I have to wonder. :P
