Mind Control... that could probably be Samantha? Maybe Samantha is controlling the zombies, Maybe she IS a zombie ( Like when we see the mangled up woman in the Tele, Teler, UGH, machines)... And she's connected to the Monkey ( which was somehow attached to Smantha), and the Zombies... Maybe the reason the Zombies hold their hands in their heads is because they are trying to resist Samantha? Maybe Samantha is trying to attack Edward because she is mad about her death? Just my thoughts. Sorry for the wall of text
