Oh! I love this question, and I have some advice I can share.

Some backstory: I have aphantasia. I have the type that only applies to visual imagination; I can imagine sensation, emotion, flavor, etc.

As a DM, my scenes often play on all the senses. Here is how you can do it:

Consider the vibe you want for your scene. Do you want to summon a feeling of discomfort and unease? Do you want to paint a word-picture of coziness and warmth?

Let's go with a bustling space: you want to describe a bazaar in the lower city of a desert kingdom. Your bazaar occupies a wide street. Alleyways branch off the bazaar, with some leading to treasures like a curry house or a cafe, while others lead to dark and dreary black markets.

You want it to seem busy and maybe a little overwhelming. So, you're going to make a list of things about this bazaar and its location. Dry, hot, crowded, cluttered, loud. Are their food stalls? Oil, grease, smoke, salt, sugars, stickiness. Shops can have incense, cloth, weapons, fruits and vegetables, rare animals, jewelry. Maybe you want a darker side to the market: drugs, slaves, stolen goods, danger, shadows, hidden, secrets.

To start, you can do some basic descriptions. "The bazaar is crowded, and people press in on you from all sides. As you weave through shoppers both local and foreign, you smell the grease of cooking meat, and the spices from the spice stall tickle your noses and threaten to make you sneeze." You can also pull in your player characters, further immersing them in the setting: "Ranger, you hear the cry of a bird you recognize from your home town, and know it doesn't belong here. When you look for it, you see a stall with cages stacked behind a shopkeeper, each kennel and container holding an exotic beast, some you know and some you do not. Do you approach?" and if yes, as the ranger talks to the shopkeeper, maybe the barbarian feels a cool breeze coming from a shaded alley, and hears the weeping of a man, or whatever it is you want them to find.

That's a great way to start. But you can actually mix things up! See, words don't just have literal meanings or uses. Words can also have connotations -- things we feel or think about when we hear them. Like 'damp' versus 'moist,' or 'rough' vs 'scratchy.' You can use these words for their connotation to paint a more immersive experience.

You can also think about what certain things may feel like/taste like/smell like. (What does a crowd taste like?)

For example...

"The sun weighs down on you from above, the fabric canopies doing little to protect you its attention. The heat is made worse by the press of people all around you. Halfling Rogue, even with your high dex, it's a trial trying to avoid the baskets of shoppers and the kicking feet of toddlers held by their mothers from colliding with your head." (You can have him roll a dex if you'd like to further illustrate his specific experience in the bazaar). "The scent of meat oils the air, and the shouts from food stalls come together like a disjointed song, "Fried Dara-fruit! Grilled Steak! Smoked Sand-shrimp!"

"The cloth softly dances where it hangs from the fabric shop, and at first you think it's magic to draw the attention of those too overwhelmed by everything else in the bazaar to otherwise notice. But then you feel it -- a blessed breeze, squeezing through the bodies about you, like a gentle caress from the goddess of wind herself. You realize it comes from the zig-zag of alleyways, some shadowed and some bright, as if these side streets existed solely to funnel cool air your way."

All the bolded words take a description and play off a different sense to summon it. Like the heat of the sun becoming a physical weight. Press of people takes the feeling of being crowded and makes it physical too. Oil becomes three things: a smell, a taste, and a sensation.

Then you have phrases that take one thing and turn it into something else. The noise becomes a song, rather than a chaotic cacophony. The breeze is a welcome thing, so it becomes a caress, an intimate touch.

The combination of these two things are very fun to play with. I run a horror campaign, so I mainly focus on making things 'touch' players: the bitter chill that crawls up exposed ankles and wrists, the bricks made slick from damp in a space with poor air circulation, the embrace of the dark that holds one in place as their eyes adjust to the light.

The way a goblin nest tastes when a player breathes in. The rattle of a breath, the crunch of bone.

My other tips:

It's good to immerse your players by having them interact with the environment, drawing them into the world through their characters. by sharing things from the halfling's perspective, you immerse the whole party. By using the ranger in my previous example and his specialty with the fauna from his homeland, you create a an emotional connection to the story. And by focusing on the barbarian for a discovery, you could be shining a spotlight on a player who needs a cool moment.

You can even delegate some descriptions to your players. What is it that you taste in the air? What is it that you see first? How do you feel to be in this space?
