Sounds: I love listening to thunder. I love listening to music, too, especially epic orchestral music like film/video game soundtracks, Two Steps From Hell, the sort of thing that just takes me to another world. My cat's happy little chirp as she walks through the door to greet me.
Smells: Weird one but I love the smell of mushrooms cooking. I suppose because one of my favourite dishes to cook is wild mushroom pasta and the smell during the whole process is just amazing. I also love the smell of lavender, new books, flowers in general, freshly mown grass (even if it does set off my hayfever) and fresh laundry.
Taste: Chocolate. Pizza. Burgers. Cake. All the junk food.

But also fruit like mango, pineapple, clementines, and blueberries.
