There’s a Metroid headcanon that will make Ocellus become traumatized for weeks.

It does. Minds work in strange ways sometimes.

Don’t worry, you’re not being rude.
 
It started when I was young (5, I think), and I believed that I would fall upwards if I didn’t have something solid to anchor myself to. Since I went to a school with a bunch of tall ceilings, I just kept imagining what it would feel like to fall upward and hit it from the inside. Being little makes it even worse, since everything seems so big in comparison to you. When I panicked, the most “comfort” I would get was having a teacher tell me I wouldn’t fall, and get me in trouble unless I acted like the other students… so that definitely didn’t help me.
 
Even when I learned that I couldn’t fall upwards, I still felt like I would if I knew I was in a tall room. It was the worst if I actually looked up, which would give me a sensation of dizziness, similar to the falling sensation you occasionally feel when you’re almost asleep. Loud rooms also echo a lot, which makes it impossible to forget how tall its ceiling is.
 
Being near a really tall structure makes me feel similarly, but it slowly gets scarier the closer I am to being under it.
 
I hope this helps you understand.

@Starry Mind  
Forgive me if I sound insensitive, but I’m trying to understand this. Why exactly is looking up scary?

I once had this fear to an extreme extent. I always looked downward while outside or under a tall roof, or stayed within arm’s length of something stationary I could grab for comfort.
 
Being under the sky was a very temporary phobia though, and it quickly evolved into being afraid of being under towering structures, especially if I look up. Tall ceilings terrified me, but within the next 10 or so years, that fear gradually went away.
 
Now I’d still not want to be under a skyscraper or huge ceiling, because it would make me feel scared and queasy, but I’m so much more capable than before.
 
This image truly brings back some interesting memories… and even moreso, since people would tease me about it.
 
“Hahaha, look up!”
