One of the most interesting findings in psychology is that cross-modal coherence makes things feel more real (e.g. see “Cross-modal coherence enhances claims of pattern presence“). This is a sophisticated way of saying that when something looks like a duck, quacks like a duck, and smells like a duck, it most certainly feels like it is a real duck.
On a similar vein, Shinzen Young points out that suffering often has various components: an inner imagery component, a physical component, and an emotional component. If you can keep them from mingling and becoming an experience that integrates all of these components at once (i.e. that is cross-modally coherent) you will be preventing most of the suffering from being actualized.
And on an entirely different vein, the reason why DMT worlds often feel extremely real can be traced back to the fact that DMT hallucinations are cross-modally coherent. Machine elves are cross-modally coherent symphonic experiences: the impossible objects of hyperspace are in resonance with exquisite “musical objects” isomorphic to them. And this makes them feel all the more real.
Now, applying this lens to the task of crafting real-looking Halloween costumes, it stands to reason that if you add a costume-consistent dimension of smell you will in turn be perceived as more real thanks to the resulting cross-modal coherence. Or, at the very least, you will be able to enjoy the signaling benefits of this new variety of artistic waste (especially for the more pricy or laborious scents).
Without further ado, here are some costume ideas for this Halloween along with their recommended cross-modally coherent scent, for which I am definitely not getting kickbacks. Really, I’m just sharing scents I like (I only talk about scents I’ve personally smelled, except for calone which I look forward to trying but am too scared to own for reasons you’ll see below, and the scent of LSD which I have not been honored to experience yet):
Oceanic: Sea Creature, Sailor, Pirate
You can go with a classic marine/aquatic cultural reference like Nautica Voyage as a blanket sea-themed Halloween costume addition. Squids, octopi, and whales are all fitting. This perfume has the advantage that its apple and green nuances won’t make you suffocate with too many marine notes.
Le Male in turn may work well for anything sailor-themed (especially if some degree of homoeroticism is welcomed).
Or for a pirate, you can add a smell of rum, either by dousing yourself in actual rum and letting it dry, or using a perfume with notes of rum like Christian Audigier For Him.
Finally, perhaps a more raw elemental and unvarnished approach would be to use calone. Without the surrounding harmonizing notes that come with the perfumes above, the way calone is described suggests it’s perceived as a definite classic “sea-breeze” smell by most (e.g. “It has an intense Marine, ozonic, sea-like smell. Pretty unique note, it can produce floral overtones. There can be a fruit aspect of melon/watermelon but it is very negligible to me.” – source). Importantly, calone is said to be extremely potent. Thus, improperly diluted, using it on your costume might make the entire place smell like a seafood restaurant, and likely not a good one at that. Then again, you could dress up as a rundown seafood restaurant.
Dune / Golem / Earth-themed elemental
Going for an easily-recognizable super-hit in the fragrance world, Terre d’Hermes Hermès for men would be a natural Schelling point for cosplays reenacting a life in vast dry landscapes evocative of Dune/Blade Runner 2049/Tatooine. Now, a very high percentage of that perfume is Iso E-Super, which by the way smells delicious in its neat form. So a much more affordable and perhaps aesthetically pure choice is to get it raw and spray it on a scarf or turban and vibe with your imaginary dry sandy homeworld.
On the wet-end of the spectrum, a little geosmin (the smell of wet earth) can give realism to a just-created Golem creature. As with calone, you will have to carefully dilute this one because it is really potent. Alternatively, you could get Demeter’s Dirt.
Fahrenheit Dior for men, either EDT or EDP, has the same gasoline note, or Shalimar by Guerlain (EDP in particular; I recommend using the EDT instead if you plan to dress up as a vanilla pudding). They all have a clear gasoline note, but smell fantastic otherwise.
Slowdive by Hiram Green is by far the most beautiful honey smell I’ve encountered to date.
Get some “Liquid Smoke“, mix with ethanol, and spray on your costume and you’re good to go. Alternatively, get Hyde also by Hiram Green for a remarkably harmonious rendition of a devilish smokey scent you can actually wear.
Personally, I don’t think there is anything more angelic than the smell of ambroxan, so get a bottle of it, dilute it and spray liberally on your wings. Alternatively, the grace inherent in the divine nature of ambroxan also means that any of these will have a touch of the angelic in them.
Late 2020 I explored how vanilla interacts with other scents. This exercise showed me that vanilla and orange scents can have a beautiful love affair. Taking it further, trying to enhance the synergy between these two notes, I arrived at the following synthetic reconstruction of the orange creamsicle quale:
3 – Orange Oil Valencene
3 – Vanillin
2 – Isobutavan
2 – Dihydrolinalool
1 – D-Limonene
1 – Brahmanol
(36 – Ethanol)
Or if you want to just get one ready-made, I can vouch that Eternal Essences’ orange creamsicle fragrance oil really hits the spot for this particular quale. Use these tools and you will be taken seriously as a bona fide orange-creamsicle-human hybrid.
If you want to dress like a lemon and you are ginger, this is the perfect scent for you: Acqua Colonia Lemon & Ginger by 4711
80s Character or Celebrity
For dressing up as a classic 80s icons (e.g. Back to the Future characters, Freddie Mercury, or Michael Jackson) Drakkar Noir is an excellent choice (note: I thoroughly reviewed it in Towards an Enlightened Phenomenology of Scent: What’s an Aromatic Fougère at the Deepest Level?). Drakkar Noir is often referred to as “The Scent of the 80s” given how incredibly popular it became in that decade. Azzaro Pour Homme would be a good substitute if a slightly more upscale fragrance is desired to evoke this effect.
That said, the only people for whom this smell will likely land will be those who were non-anosmic youngsters in the 80s and who are still non-anosmic today, namely, Generation X people. Make sure to invite some of them to your party.
Die-Hard Inner Circle OG 60s Hippie
And finally, if you want to go one step above your generic tie-dye hippy (such as an actual member of the Brotherhood of Eternal Love, the sort of people who literally do thumbprints of LSD), then an idea would be to douse yourself with something that literally smells like LSD. Yes, it turns out LSD has a smell. And Sigma Aldrich sells samples of an LSD-smelling substance (“Substitute for controlled substances in the training of narcotics detector dogs. Mimics the odor of LSD”).
And that’s it for now! I hope you have a wonderful and cross-modally coherent Halloween!
Doe anyone have an idea of how to make an essential oil fragrance that smells like “dank” cannabis … without actually having any cannabis in it?
Big thanks for any suggestions!
Look up “Terpene dank weed” on Amazon and you’ll see some products. If you want to go for the raw and unvarnished approach, some linalool, humulene, and d-limonene diluted in ethanol will go a *long* way (e.g. get “Elevation Terpenes Energy Pack Four Pack” which I sampled last year think is high-quality). All are obtainable on Amazon and sites that specialize in perfume ingredients.
