Halloween isn’t complete without a marathon of spine-chilling classics — the kind that make you check behind the sofa, turn on the lights, and question every creak in the house. Luckily, OSN+ has a lineup of horror legends that’ll keep your nerves on edge and your popcorn flying. From supernatural hauntings to blood-soaked prom nights, here are the top 5 movies you need to stream this Halloween.

1. The Conjuring (2013) — “Based on True Events” That Will Ruin Your Sleep

Before there was Annabelle or The Nun, there was the film that started it all. The Conjuring follows real-life paranormal investigators Ed and Lorraine Warren as they confront a dark presence haunting a farmhouse in Rhode Island.
It’s atmospheric, expertly paced, and full of old-school scares that rely on tension rather than jump cuts. Every flickering light and distant clap feels like a countdown to your next scream. Perfect for those who love supernatural horror with just enough “based on a true story” energy to make you question everything.

2. IT (2017) — The Clown That Redefined Childhood Trauma

Stephen King’s nightmare fuel comes to life in Andy Muschietti’s terrifying take on IT. Pennywise the Dancing Clown (played with nightmarish perfection by Bill Skarsgård) stalks the kids of Derry, Maine, feeding on fear — and occasionally, the odd child.
It’s a mix of coming-of-age adventure and pure horror chaos. The Losers’ Club’s friendship gives the film its heart, while Pennywise’s grin ensures you’ll never look at red balloons the same way again.

3. The Exorcist (1973) — The Grandfather of All Possession Movies

It’s been 50 years, and The Exorcist still hasn’t lost its power to disturb. Regan’s possession by a demonic entity remains one of cinema’s most terrifying transformations, and the film’s blend of psychological dread and religious horror still hits hard.
With unforgettable imagery — from the spinning head to the priest’s desperate prayers — it’s no wonder it’s regarded as one of the greatest horror films of all time. Watch it with the lights off… if you dare.

4. A Nightmare on Elm Street (2010) — Don’t Fall Asleep

The 2010 remake of A Nightmare on Elm Street brings Freddy Krueger back with a darker, grittier twist. This time, Jackie Earle Haley (of Watchmen fame) takes up the burned fedora and bladed glove, delivering a version of Freddy that’s less wisecracking and far more sinister.
The film reimagines Wes Craven’s original concept with modern visuals and a heavier psychological edge — diving deeper into Freddy’s disturbing past and his victims’ shared nightmares. It’s slick, brutal, and drenched in dread — the kind of remake that makes you nostalgic and uneasy at the same time. Just remember: the moment you drift off, Freddy’s waiting.

5. Carrie (1976) — Prom Night Never Looked So Bloody

Before Mean Girls, there was Carrie — the ultimate cautionary tale about bullying, puberty, and telekinetic revenge. Sissy Spacek’s haunting performance as the shy outcast turned avenger is both heartbreaking and horrifying.
Brian De Palma’s adaptation of Stephen King’s first novel is slow-burn perfection that culminates in one of the most iconic finales in horror history. Just remember: never mess with the quiet kid.
