I did not dream of a kid dreaming of the Knights of the Round Table,
But let’s daydream that I did for the sake of the story in my head.
Because, after all, he was daydreaming, not sleep-dreaming, because his sleep dreams are either nonsensical or unremembered, which is all to the good.
And he was daydreaming when the accident happened.
In his unconsciousness, then, he was Sir Bedivere, strong and true. Not an awful place to be when the alternative is a hospital room with fluids draining and others pumping in and no darkness ever.
