Insidious

It's not the house that's haunted.

When their son falls into an inexplicable coma, Josh and Renai Lambert learn he hasn't simply fallen asleep—he's wandered into the Further, an astral realm inhabited by malevolent entities. To bring him back, they must confront the creatures that hold him captive and banish the supernatural forces haunting their home. A dizzying descent into the spaces between worlds unfolds.
