nothing is scarier than coming back to this video years later and seeing comments from me in the third grade

@Defluo619

It makes me sad that no one talks about how visually appealing this video's art style is

@rucealexander2848

many comments are relating this to sleep paralysis, but I have anxiety dissorder and I can relate to these lyrics during my panic attacks. Honestly I'm sure that this song is meant to be interperreted in any way

@BuersPs4lm

The “hiffu hihifuffu” is a onomatopoeia for breathing. I’m guessing that the person who wears a mask had a hard time breathing or it could be an anxiety attack.

@peachetaffy1203

The catchy ones are always the darker ones?

@trickiieyes

She's probably panicking witch leads to hyperventilation

Lack of oxygen can make you hallucinate and do strange things .

Or its a night terror

@ronniespavale2922

Fun thing about this song is that it barely gives you time to breath in between verses so it would probably be hard to sing in one go

@kirlia34

This song is about what it's like to have an anxiety attack. 
The mouths are representations of the negative thoughts she has about herself (which is why they say "BAKA").
The pain comes from the attack itself, since hyperventilating for a few minutes makes people very light headed. It can make people feel like they're floating and/or that they're dying. 
The scary figure comes from paranoia that anxious people have, they worry about anything and everything that could hurt them.
The double mouths dancing at the end could represent that she's at a point in her attack that she can't think rationally at all anymore, and that's why she's not being shown. 

But meh, this is just coming from someone who has attacks, so I might be biased.

911: 911, what's your emergency?
me: SOME LIP MAN IS AFTER ME

@hayz691

I used to have respiratory problems when I younger. Hyperventilation was the more uncommon one to happen, but the three times it did happen in my childhood is still fresh in my memory. I remember how much it hurt to breath slowly, and how my sobbing made it worse. I'm glad I don't get those too much anymore :D

@cherryzombiezz

This song gives me a strange sense of nostalgia.

@mikudayo_biggest_fan3939

why is no one talking about how satisfying the guitar is?? all around the song like it’s so beautiful

@anonimusferentari

I like it when she sings "Hiffu Hihhiffu", it sounds so nice C:

@honeyswann

This song makes me feel like when I’m very anxious at night and I hear commotion outside. I don’t live in the best of neighborhoods so it happens often and I still get anxious. I end up making up bad events in my head that keep me awake and make me panic. That’s how I interpreted this song, as just horrible anxiety.

@dissapointment.

as a person who has anxiety attacks almost every day, this song is what it feels like to have an anxiety attack, it hurts

@zhnigo

2:50 this also sounds like "ichi, ni, san, shi" or "one, two, three, four" - a nice double entendre

@brattyz

she became one with the giant mouth people

@myosotix4485

i know that the general consensus is that this is about an anxiety/panic attack but this resonates SO hard with me as someone with asthma... the struggle to sleep because you can't breathe, all your other senses heightened as a result (the part about becoming zombies), the sirens could easily be an ambulance, lack of oxygen can cause hallucinations (like the grim reaper), and many people have died very slow miserable deaths due to asthma attacks. its rough. 100000/10 nashimoto song

@Touhoulicious

It's MY mental breakdown and I get to decide the background music

@roserocksrapidly

This song makes me all self-conscious about breathing o.O
