Jeff the Killer is one of enemies in Creepypasta Land.
Evasion strategy Edit
When you interact with him he will say "Go to sleep..." You are givin two options to either Run away or Pray. If you chose Pray and he will remark that he will kill you next time and then he disappeared. If you chose Run instead, he will say something about going to sleep before killing you. He appears in your first dream where you have to get caught by him before waking up.
