What is that weird message and why?

[GhostXIII]

I wish I could screenshot it, but it's only happened twice, and it's very brief, and random

It's almost like a pop-up but ingame, part of the game, and in an alien script. 

Kinda looks like the elvish on the Ring of Power, but way scrunched up.

Also, the first part is white, and the 'response' is in a red.

Then it just disappeared.

Anyone have a clue what this is and how to get it to happen again?

Every single one I've encountered has actually been the same text.

Tenno language. Already been fully translated. Relates to the second dream quest. It was first put in the game to hint at the second dream. Its a bit spooky. It has a very slight chance of appearing during mission loading screens.

There are more than one message, first was for 2nd Dream, one was for a Tactical alert, another was Shadow Debt, and another might be referring to upcoming content.

Wow, that's actually really cool. But is it random, or triggered by someone that was in my group?

Because now that i think about it, the first time I saw it, I was about to start the second dream or already in the process of it.
