Is it normal that whenever i sing i get sleepy?
I've been doing chorus and singing since i was in 4th grade. Never once had i noticed this strange feeling until this year. Whenever i sing i catch myself falling asleep! During show choir i was singing my voice part and i didn't notice it but my eyes were getting heavy and my vision turned a bit blurry like when you're about to fall asleep and i had no thoughts in my head. I have enough air to sing but is this normal or what?
