Be prepared to never sleep again.

Don’t say we didn’t warn you – thesehorror flicksare not for the faint-hearted.

But we did it.

Seriously, you don’t understand.

This 1973 classic is what started it all.

What makes it even scarier is that it’s loosely based on actual events.

Her only glimmer of hope is a priest who requests to perform an exorcism on Regan.

Not only is this movie terrifying, butits special effectswere also well ahead of its time.

That puking scene with Regan in her bed is too much for some people.

All of this is true, by the way.

The Warrens are real people and the Amityville murders really happened.

Paranormal Activity (2007)

Sometimes, the movies with the smallest budget make the biggest impact.

Evil Dead

Just look atThe Blair Witch Project.

The firstParanormal Activitystarted with a budget of $11,000 and earned $193 million for Paramount.

Again, no biggie.

Wouldn’t that be a deal breaker for some?

Anyway, this demon is back with an angry vengeance.

Okay, now this is where things get confusing.

We really can’t pick which is better.

Yeah, cause that always goes well.

Oh, did we mention that it’s inspired by true events?

The rolling end credits are accompanied by pictures from the police report.

Local officers reported that they saw a “situation of mystery and rarity.”

Analyze that any way you’d like.

The Amityville Horror (2005)

The true horrors of this movie lie in its backstory.

Like DeFeo, the Lutzs also reported hearing voices and seeing paranormal figures.

It got so bad that they moved out in a whim without ever returning for their furniture or belongings.

Come on, how can a movie about these events possibly be anything less than alarming?

The Exorcism Of Emily Rose (2005)

It’s not a happy ending for Emily Rose.

Ouija 2

Ouija: Origin of Evil (2016)
