This is all super symbolic as usual... They obviously use white masks to exclaim they're on the good-guy side. White masks, white ghosts, all reoccurring themes. If it was black mask, it wouldn't have the message it does, would it?

Space and the cosmos represents exploration and independent thinking. They are expressing the need for people, (as well as themselves I'm sure), to expand our thoughts and the field of view.

"Many everyday things become associated with those primary stimuli" ""A Belief""

At 16,17 seconds coincidentally, there is the figure of a man but the head is actually a goat if you notice the horns, definite symbolism. Moloch immediately comes to mind obvs, & the goat traditionally represents a lack of judgment and gullibility. Alternatively, goats are symbolic of sexuality, sexual desire, lechery, and of course, sacrifice and satanic ideas.

This goat man is preceded By "behind every Idea" and Flames, goat looks onto the burning scene, and "A belief" is also shown in flames. Flames are flames. They may symbolize purification. Mostly tho, they symbolize destruction, passion, desire, illumination, purification, transformation, enlightenment, or anger. Just as "fighting flames" means it will take the best efforts and energy in extinguishing the issue. Fire may also be a metaphor for "flaming" or some heated argument or personal attack. Flaming also may refer to someone who is overtly gay, I.E; u. :)

Time is obviously a factor in anything. All that is good takes time, time is running out.

On the watch is a blatant chess piece symbol. Chess as we know, is a representation of the battlefield against the evil. White and black squares signify the Pros, and the Cons of the situation even. Every move must be calculated 3 moves in advance. The particular piece is called a Knight, for those that aren't kin to board games.

The knight represents the pure inner-warrior. If a knight starts out passive, it will always end up aggressive and vice versa. It can't move very far, but it never moves in a straight line, always preferring to be tactical and thoughtful. The Knight signifies honor, loyalty, protection, security, strength, courage, and honor.. The knight can be seen as a savior, "Knight in Shining Armor"

Then we seemingly have a mannequin, stone cold expression, eyes not opened, and this head seems that's its been battered by something, evident from the rough surface. Consequently, this looks eerily similar to the "NPC" grey man from the meme. The head also has a tri colored flag Blue, White, Black 3 bar flag with an olive branch as a backdrop.. No expression, eyes closed and in the flames... then

"Partly by a process called conditioning"

The flames disappear, a serene blue light appears below left of the face immediately followed by a light turning on above the head, signifying an idea or an awakening.. Turning on the lights in peoples head, light in the darkness, light at the end of the tunnel, etc etc.

"You know what? I like that Idea."

Knock knock obv symbolizes they are at the doorstep of whomever they are dealing with.
