I must be stupid, but I didn't see any associations with the mirror... The cache probably just guessed by listing, or based on one picture.
Which makes me think that your associations are a bit strange...
The point of the game is not to understand the author's twisted logic, but to make that logic simple, but due to the volume of associations from different areas of knowledge, it would be difficult to build their intersection right away.
The 3rd picture is from the movie REFLECTION, Victor deciphered it amusingly, I won't tell you the rest for now, I'll decipher everything after the next riddle/when I find the pictures, if you're interested.
to PReDS, don't get too excited, I've already corrected myself in guessing the pattern :D and exciting battles in the qualifying round!!!
