When I hear certain sounds, they elicit emotions.
The sound of Aluminium Foil feels like abject fear, it cuts through me and hurts my soul. I literally get the Fight Or Flight response whenever I hear it. Similarly, Deep Booming Bass (slow) feels like home, makes me feel safe, and calm. The Texture of some plastics feels like Anger to me, I feel rage bubbling up through me when touching some fabrics or plastics (especially the seams). Latex and PVC however feel like lust... maybe that is more to do with my personal fetishes, but they do. A woman wearing Latex or PVC feels like lust, I don't even have to see it, I just FEEL it. Silky fabrics feels like Love, like a lovers embrace. When my partner wears anything silky, I find it VERY hard not to grab a hold of her and just touch her... Sometimes the temptation is overpowering. Some textures make me feel things, some sounds make me feel others. I can taste the sounds of some things, and I can smell the colours of others. Some of it good, some of it bad. The taste of some things remind me of the smells of others - Olives, the fruit not the oil, tastes like Cat Piss Smells... and it is disgusting to me, like Gut Wrenching levels of Ewww.
The smell of Citrus fruits feels warm, the smell of Mint feels like a summer day, Cat Piss smells like Olives Taste... Nasty nasty Olives Ewww.
Then there are the memories triggered by some things, and the effects that has on me. I was walking around the local supermarket the other day, and a smell hit me from in the Fruit and Vegetable section, and I swear, I not only got Deja Vu, but I got location dissonance, full blown "Had no idea where I was" hit me. It took me a moment to remember that I was where I am, and that I was not in a supermarket in Sommerset England (I am in Northern Ireland... not even the same damn island, let alone town).
Music is like this too. Music is an integral part of my life, it regulates my thoughts and emotions. I often get lost in the myriad of random thought streams that are concurrent in my head, and music always helps order them. Some music makes me feel safe, some energetic, some feels like nails on a chalk board, like someone is hammering at my head, but for the most part, Music is a pleasant experience, and grounding. Textures too, sounds, smells, and even images. I often wonder what it feels like for others, I know there is an entire community of folks dedicated to sounds making them feel things, and you can go down a very deep and dark ASMR rabbit hole on certain video provider sites.
Sometimes this can be very extreme, other times its just a gentle nudge. It feels entirely natural and normal to me most of the time, other times however, not so much. I have no control over when it hits, no idea how it will hit, it just will.
Textures as Emotions, Tastes crossed with Smells, and Music to move a Mountain. We all perceive the world differently, how you see and feel things is different to everyone else. Life is a rich tapestry of weird and wonderful colours, sights and smells... except for Olives, you can keep those.
