One was basically a zombie movie (I must have seen one on TV or something) where people are slowly being transformed into zombie like monsters, and the nightmarish punchline was my dad turning into one.
Another was being chased by an ape along a pier which forced me to fall in and start drowning to realise a hoard of spiders were swimming down into the water to get me (haunting final image that one).
Another one was my newborn brother in a pram being let go from the top of a hill and me running as fast as I can to catch him.
