I think there should be one that gives you the feeling of goosebumps, like sending a shiver down your spine, and the prickly feeling, that would be pretty cool.
My favorite ones are QuickHappy, Nitrous, and French Roast. So i would like to see many more shorter ones.
Goosebumps
Piggybacking off of your post, it made me think of a "QuickHorror" dose; one similar to QuickHappy, but instead causing an instilled sense of paranoia and thrill. I would be interested in a dose that would cause a quick burst of fear, but unfortunately I believe if hallucinogenics was added to make a true "Haunted House" dose it would have to be much longer than simply 5 or 10 minutes.
