Since you guys want to be serious about this, I am surprised nobody has mentioned planting suggestions beforehand to set the mood, perhaps with a note secreted someplace they are sure to find hinting at what is to come, or perhaps slowly dropping hints to confuse/arouse/terrify someone prior to getting together.  Or of giving some instructions for a task in the same vein.

Or of setting the mood by throwing the furniture around and throwing things on the floor so when she comes in and you are wearing a mask...

Even just a blindfold accompanied by strange unknown sounds or even voices could be interesting
