During the song, Olaf is on his own in the woods . Unexplained phenomena keep occurring around him so he comforts himself by saying that the events will make sense when he's older. After a series of encounters, including one with the Nokk, Olaf is swept up by a tornado.
Olaf: What was that?! Samantha?
This will all make sense when I am older
Someday I will see that this makes sense
One day when I'm old and wise
I'll think back and realize
That these were all completely normal events!
I'll have all the answers when I'm older!
Like, why we're in this dark, enchanted wood
I know in a couple years
These will seems like childish fears
And so I know this isn't bad, it's good
Growing up means adapting
Puzzling at your world and your place!
When I'm more mature
I'll feel totally secure
Being watched by something
With a creepy, creepy face
See, that will all make sense when I am older
So, there's no need to be terrified or tense
I'll just dream about a time
When I'm in my aged prime
'Cause when you're older
Absolutely everything makes sense!
This is fine
