What could these symptoms possibly be of an illness?

First, I'm not a native English speaker please understand. A year ago, I was sitting in class, jotting down things into my notebook then I noticed I was seeing white spots all over the place, and I knew they weren't actually there. After the class ended, my head was hurting like hell. I have a bad sleep schedule so this regularly happens. I didn't think much of it and thought maybe it'd get better if I laid down and took a nap. I was listening to music as I laid. As I was laying I began to stop understanding what the lyrics were saying. It was weird, so I sat up, looked down at my textbook, then I couldn't understand what the words on it were. I was panicking. I went outside thinking it'd get better but it didn't. I started freaking out and crying so I went over to my friend and asked her to help me. She was confused then told me to try to speak or write something down. Fyi, I know three languages fluently. So, I tried to write something entirely in Khmer but the sentence would be of all three languages involuntarily. I couldn't read, I couldn't speak, if I could they were just gibberish and a bunch of incoherent speech. My ears were ringing, whatever people were talking to me It comes as an echo. I could understand but couldn't get my words out at all, I was completely tongue tied. I heard that this might be a stroke? It happened once, and I'm just curious about this. Please be kind!
