In a new trailer tinyBuild put out, Hello Neighbor is showing just how terrifying things will truly get while playing this stealth-based horror game about exploring your creepy neighbors home.

Hello Neighbor being a nod to the Rear Window people know and love is a little stranger than it lets on to be. As seen in the trailer, things go from zero to sixty in no time flat, with dream-like sequences playing out or what could be alternate realities. Hello Neighbor looks to be one hell of a ride, and whatever the neighbor is hiding is more than just bodies.

See how horrifyingly weird things get in the trailer below. Hello Neighbor arrives on PC and Xbox One on December 8.
