10 Terrifying Movie Monsters That Barely Appear

Joel Anderson's found-footage horror explores the death of a 16-year-old, Alice Palmer, who drowned in Lake Mungo. Believing her spirit is attempting to make contact, her brother Mathew set up cameras around the house, seemingly capturing Alice's ghost in her bedroom.

When Mathew confesses he faked the footage, it looks like the whole haunting was a sham, but after spooky activities continue to happen to the Palmers, it becomes hard to tell what's real and what isn't.

Travelling to Lake Mungo, the Palmers discover Alice's phone and watch the last video she recorded. In this clip, Alice is walking along the shore when a mysterious figure marches towards her. As this person comes into frame, it's revealed to be a doppelgänger of Alice. Stranger still, this duplicate resembles Alice when her body was later found, including the bloated skin and malformed face.

This moment is absolutely skin-crawling, not just because of the morbid image but also for proving beyond any shadow of a doubt that the supernatural occurrences the Palmers have experienced were real. Most bewildering of all, it's never explained what this doppelgänger is or why it appeared.

Despite only appearing for a single frame, Alice's corpse-like double is sure to be seared into viewers’ brains for a long time.
