The Nightmare Sans wasn't waking up for Error. So Error called Dr.Dream to the house instead of going to the hospital for his check-up. Dr.Dream showed up to the house ten minutes later with his medical bag. Dr.Dream shook Nightmares shoulder and Nightmare Sans woke up with a confused look. "Did I forget something?" "Yes, you did. You have a doctors appointment with me today. I'm here to give you a checkup." "I'm sorry." "It's okay you were probably tired and coughing a lot last night." "True." After Dr.Dream checked out Nightmares health. "He has the flu and very high blood pressure with it. I'll give him something for the flu and his blood pressure." "Okay, I will take good care of Nighty." After Dr.Dream left the house the Error Sans sat by Nightmare Sans bedside. The Error Sans fell asleep in the comfy chair that night. The next few weeks past because Nightmare started feeling better. Dr.Dream checked out Nightmare Sans one more time and said he was good to do whatever he wanted. The Error Sans went to bed that night and Nightmare went to his own personal room to sleep in. The next day, Nightmare woke up and went to eat breakfast with the others. One person was missing from the table and that person was Error Sans.
