A woman I know IRL had an experience like yours. One of my friends had given birth a few days before this woman (who was a sort-of friend to my friend) came in to the hospital in established labour and she was already screaming and crying and basically had very little control over herself. It only got worse as her labour progressed apparently and this women did ask my friend to go into the labour ward with her and she declined, but she said the whole time she was in the labour ward you could hear her continuing to scream and carry on. Although she did say she must have tried the gas at some point becuase the screaming turned into hysterical laughing for a little while. So no, you're not alone, but I imagine that you never see videos of births like yours because I guess people think women don't want to see that?
