It’s actually normal.
Your nostrils cycle between like this so that the one can take a break from the air flow and mitigate drying out.

If it’s normal, why does it bother me so much? The feeling drives me absolutely nuts and I hate it.

Hey that’s just part of becoming aware you’re a sentient being stuck in a weird meat vessel that’s just full of undebugged closed source code blobs.

If you’re slightly congested, it sucks more.
If you think about it too much about your breathing, it sucks.
Otherwise it’s fine.
