People assume that The Haunted Mansion is a strict progression of walk-through to Doom Buggy tour, but actually, from a nonlinear, non-subjective viewpoint, it's more like a big ball of wibbly wobbly tombstone...stuff.
The backstage areas of The Haunted Mansion (at least, the ones easily and non-trespassingly accessed by a guest) look like the setting of a horror film. Thankfully, I was not murdered by a violent psychopath in this corridor. These vaguely sort of (I guess?) themed directional signs are remarkably charming in their cheapness.
