This song is called Brain Flower. It's about how we interact and learn, but we'll never know certain things we want to know.

Lyrics:
Watch the mind's complex imagery
Bloom approaching thoughts
The memories inside are matterless
But flow on caught

Within a rift of time and
interdimensional cost
Nostalgic notions climb a wall
That's scaled with pain and frost

A brain that flowers unlike most
has random patterns fly
A new beginning one can learn
Is better than a lie

Link together
Filled with feathers
Yet heavier than life
The meaning fills itself
With doom that blinds
What makes you bright

One idea that wraps around
Your finger dwells a bit
Laying down the edge is near
The deep entombment kit

A visage darkened by the light
spills words that you can't place
Lacking vile implications
Heals and wards its face

A brain that flowers unlike most
has random patterns fly
A new beginning one can learn
Is better than a lie

Link together
Filled with feathers
Yet heavier than life
The meaning fills itself
With doom that blinds
What makes you right

Void of all emotion
Shielded from itself
A form - a polyp of sorts
At the highest shelf

(Break)

A brain that flowers unlike most
has random patterns fly
A new beginning one can learn
Is better than a lie

Link together
Filled with feathers
Yet heavier than life
The meaning fills itself
With doom that blinds
What makes you bright
