Draw the top Mythos card from the deck and resolve it. Then place it on a faceup discard pile.
NOTE: The Recurring Trauma insanity has an investigator keep a previously drawn Mythos card in front of them. Mythos cards may have several different steps to them, divided into 3 types. You must do these steps in order, from top to bottom, before discarding the card. If you can’t do a step on the card, skip it and move on to the next.
