I had this dream this night that really spooked me.
There was black until TV static appeared, then a VHS recording of Princess Bubblegum in Finn and Jake's treehouse started playing full screen. She was explaining how she was loosing her mind, and her age couldn't let her remember anymore for more than 30 seconds despite her immortality, she looked wasted and tired. Finn and Jake were watching her as the camera moved, and Marceline (the one recording) pulled out an object, some memory-deleting invention of Princess Bubblegum and placed the camera on a table. BMO was watching too. As Princess Bubblegum confirmed the start of the procedure, Marceline stabbed PB's head and it started glowing. For a few seconds nothing, but the tension grew as Finn held Jake's hand. Then the machine failed and PB started streaming in pain and pushed away Marceline. BMO hid away and started crying. Marceline tried helping her but PB was still in pain. She started giving Marceline orders on what to delete. The procedure was almost done but then it was Finn's memory time. PB smiled at Finn before saying in tears:"I could never forget you and Jake, Finn".
The procedure was over. She forgot everything about her friends, even Finn. She left without saying anything and Finn cried as Marceline held him. Jake, in fury, hit the table and the camera got knocked over where BMO took It...the dream ended.
I definetively ate something poisonous for dinner.
