Dream logic (or The Plot Thickened, and then thinned as if a gallon of water had been added)

In Which Our Hero Realises He Has Taken A Wrong Turning

You know when you have a dream and you're convinced when you wake up in the middle of the night that it contained the complete plot for a novel? Then you wake up in the morning and realise you're an idiot. Here are the plot elements I can recall: A man with a serious injury to his torso who has to look after a cattery with only two cats, but he needs to fly to America only they won't let him onboard a flight. So anyway, he gets to America, and there's an artifact, some museum piece... (this is how my memory returned to me this morning, in instalments, and it's sounding weird, but do-able so far, but then... Oh but then!) The museum piece is MAGIC! Oh dear. At least there was a chase through an elegantly furnished hotel to enjoy after this.

That is all.
