This is both correct and natural. You will hear native speakers use the exact same wording. We also often times use the words "dream" for unrealized desires.

Hi Francesca, I see this is for your italki bio, right? Generally there's absolutely nothing wrong with the sentence you've written here. Allow me to share a personal suggestion, though: "This is one of my greatest aspirations in life." Now, the purpose here is not to use as many complex and advanced words as we can - but rather to make use of as much of the language as possible to express ourselves in the clearest way we can :) Hope this helps! Also, you can say here "how can I make it sound more natural" instead of "soundS".
