Does this game have a time limit?

[Longknife]

When you sleep, sometimes a companion wakes you saying you're acting crazy. Over time this seems to get worse, with them acting as if it's growing more and more dire.

 

  Is this merely flavor? Or is this actually meant to tell you "hurry up or game over?"

[Sonntam]

There is no time limit, don't worry.

You will start to see progressively crazier things tho
