Death and All His Friends

Someone deciphered the code:

Y ? ? | ? p a u s/z e k I have no idea what I'm doing haha

One thing that's for sure is that I see two words with 3 and 7 letters.

It also looks a bit like braille

I guess I'm too enthusiastic haha

So this is from Alien Radio FM. Maybe it has a relation with the X&Y alphabet?

The Dutch audio fragment from Alien Radio FM is just an episode of Alice in Wonderland....
