I've had a few dreams with a recurring theme where I'll go on a vacation, and for some insane reason I bring all three of my cats, who proceed to lose their shit and run off, I end up in some kind of Benny Hill-like escapade trying desperately in vein to catch them, which is funny in retrospect and very stressful during.
In one of them we were on a cruise ship on the top deck and one of my cats jumped over the railing to escape, not knowing it was open air beyond, she definitely died. I basically screamed until I woke up.
