Thank you! Yes, I am in the process of giving the player multiple options when it comes to encounters. "Drugged isekai" is a new concept for me too. I guess that is what the game is about, but I just took it from Lovecraft's stories :)
It's based on the "Dreamquest of Unknown Kadath" but the part about taking "herbs" is also mentioned in "The Silver Key" and "Celephais" where people are trying to stay asleep longer to accomplish something in a dream state...
