you are unable to yell during a dream? Ive had a lot of dreams where something shocking happens. I really don't remember the details but I do remember my inability to yell, as hard as I tried. i would try 3 or 4 times and at the last try I usually suceed in yelling. Not meekly, but it isn't powerful. I have to yell again.

I tried searching aroudn for an interpretation, The dictionary meaning for yelling doesn't include "not being able to yell".

I'm curious abuot this because dreams tend to reflect yourself. Or atleast in my experience it does, I can't say for everyone else. But when something shocking happens ive always been the type of character that reacts. I rarely hesitate and I don't have a problem yelling when I need it.
