This Translucent Mask

I've wrapped my head in cellophane to preserve my thoughts.
I can't breathe but I don't know if it's more important to stay alive
or to keep what I know from the world.
This translucent mask contorts my expressions.
I look just like I do when you see me in your sleep.
You know it's me but you're not sure why.
Could be my voice but it's never my face.
