This is exactly how I remember it.

I dove deep into the dark water, fighting for the light and life of the surface even as white-coated people below tried to drown me. One had me by the throat, holding my face still, as another forced water up my nose.

I was all so horrifying and obviously nightmarish that I decided I must be dreaming. So I tried to wake up. But I couldn't. I tried all the tricks of lucid dreaming. None of them worked. The last thing I remember thinking as I choked for air was, "From some dreams, you just don't wake up."

That's exactly how I remember it. I was later told I yanked out four nasal tubes before the white-coats stopped trying to insert one.
