Since 2018 (i was 18) i've been having strange, 3-5 second long intense episodes where i can't understand language. on top of that, every sound (and i mean every sound) is perceived as a word/vowel. for example, a snap of a finger sounds like "mack"

You have described, it is possible that you are experiencing a rare condition known as "Transient Epileptic Amnesia" (TEA). TEA is a type of temporal lobe epilepsy that can cause brief episodes of memory loss and confusion. During these episodes, individuals may have difficulty understanding language and may experience sensory distortions, such as hearing sounds as words

Definitely worth exploring with the help of your doc, your symptoms are suggesting a possible absence seizure variant that will have to be ruled out.
