Dream About Singing In Bathtub

In my dream, which was very vague, i was sitting in my bathtub with the shower curtain closed and no water in the tub. Someone was on the other side of the curtain, unsure who as i couldnt see, but they felt safe and female. I started singing light codes, something i have yet to figure out in the waking world. I remember my voice cracking as a sang, but rather than being embarrassed i recognized where the shifts were happening and that my imperfection was perfect
