Since the beginning of Haven we have all made dream catchers to get dreams for curios and hearth fires. But with every dream comes a nightmare.
I propose that when harvesting a dream catcher there is a random chance to harvest "A Horrible Nightmare" instead of a beautiful dream. This would work
in context with the catcher as there original purpose was to catch bad dreams in its web.
"A Horrible Nightmare" would be a rare harvest curio like a death's head chrysalis but less common.
