Horror films are known for their ability to send chills down the spine, but some are so frightening that you can’t watch them alone. Here’s a list of particularly terrifying movies that are best avoided if you’re alone:

1. The Conjuring (2013)

This film revolves around a family haunted by a malevolent presence in their home. The suspense and fear are so palpable that watching it alone could be overwhelmingly frightening.

2. Oculus (2013)

Oculus tells the story of a sister who tries to help her brother overcome disturbing thoughts she believes are caused by a cursed mirror. The psychological horror and disturbing atmosphere make this movie especially unsettling for solo viewers.

3. The Babadook (2014)

The plot centers on a widow helping her son confront a monster from a children’s book. As the story unfolds, it becomes clear that the child’s fears may be rooted in something real rather than imaginary. This added twist makes the film even more chilling.

4. Insidious 2 (2013)

The sequel to the popular Insidious series continues the eerie tale of a family attempting to rid themselves of a haunting from their past. With its intense atmosphere and frequent scares, it’s a daunting watch alone.

5. The Autopsy of Jane Doe (2016)

This film follows a father and son who encounter horrifying events while performing an autopsy on an unidentified corpse. The disturbing imagery and unsettling discoveries throughout the movie make it a particularly intense experience if watched alone.

6. Under the Shadow (2016)

Set during the Iran-Iraq War, this film tells the story of a mother and daughter dealing with supernatural occurrences in their home. The tension and dread in the context of a war-torn environment make it particularly frightening when viewed in solitude.

For a less terrifying experience, it’s wise to watch these films with friends or family. Their intense fear-inducing elements are best shared.
