Were these seizures?

When I was a child probably 8 or so I remember something strange happening. I was in the living room at night watching TV with my brother, we would often have 'sleep overs' in the living room on the weekends. He was asleep already and I was just lying there bored. I remember starting to feel scared and my voice in my head starting going really fast? That's the best way I can describe it. Then I heard what sounded like a giant ball rolling down the hallway towards me it was SO LOUD. But maybe it was the ceiling fan above me I was hearing really focused in and loudly? This may have happened more than once but I just can't really remember. Then when I was 15 or so something very similar happened. It was before school and early in the morning. I was sitting on my bed brushing my hair. All of a sudden the voice in my head began going really fast almost like it was panicking and screaming. But I couldn't make anything out. I know this sounds confusing. I remember my vision was sort of zooming in and out? I just remember feeling really scared. I heard the loud noise again and I have a ceiling fan in my room so maybe it was that? I don't really know. It might have lasted just a few seconds or maybe a few minutes it was really weird. I remember running to tell my mom after and I was so scared. I thought I was losing my mind. She didn't really know what to say, I guess she kind of just rolled her eyes at me. I have always been an anxious person so I was always going to her and exaggerating and freaking out about something. As I said I have a lot of mental health issues (anxiety/depression/ocd) so maybe it was related to that? But I've had panic attacks and this was nothing like that. I'm now 22 and it hasn't happened since but I think about it often because I just have no idea what it was.
