<span class='standouttext'>Spoiler : </span><span class='spoiler'> </span> The goal in the House of Madness is simply to escape, and you'll receive a clue in the very first room when a disembodied voice tells you to "sleep."
There are only four rooms in the house, so it probably won't take you long to wander into the bedroom, but if you want explicit instructions: from the starting room click on the north door to enter the kitchen, pick up the key there (on the eastern side) and unlock and go through the door to the west. That will put you back in the starting room. Then click on the door to the east to end up in the bedroom. When you click on one of the beds, you'll be teleported back to Iona's Dungeon
