As you enter the Haunted Mansion the first room you are lead to is the portrait hall where you are treated to an optical illusion in which you can't figure out if the floor is descending or the ceiling is rising. Next, you board a "doom buggie" and begin your trip through the mansion. As you voyage around the mansion you will encounter 999 ghosts and ghouls which are displayed with both special effects and in scary exhibits. At the end of the ride you pick up a "hitchhiker" in your doom buggie- a ghost which you can see sitting beside you as you look into the wall of mirrors in front of you.To keep the Haunted Mansion looking old and dusty, Disney employees have to apply coats of dust to the mansion on a daily basis.
