At this point it wasn't clear which it was going to be so I played along.
Does this ever happen to you in your dreams? That you're somebody else, like an actor in a real-life story trying to move with the flow of the situation unfolding around them? Or are you always yourself?
(To be clear, I didn't actually believe I was a little old lady, but to everyone around me I looked like it, so I acted like it too. For the sake of seeing how the story continued.)
Edit: Thank you for your replies, everyone. Hearing about what others dream about (literally) is very interesting!
