I need some horror movies to watch

Dora the explorer
Doraemon the movie
Many more

Rosemary's Baby, really great

i recommend you to watch the conjuring 1, the conjuring 2, the conjuring 3, the nun

Anabelle series for sure, im sure you will spend hours watching

cabin in the woods not that much of a horror but it's worth it

Midsommar is one of the best horror films I have watched in years.

I haven't been able to find many good horror movies lately.. not since the masterpiece of insidious. They all feel stale to me

The Exorcist (1973)
Hereditary (2018)
The Conjuring (2013)
The Shining (1980)
The Texas Chainsaw Massacre (1974)
The Ring (2002)
Halloween (1978)
Sinister (2012)

i can also recommend the conjuring movies.
The boy / Brahms might be to consider.

you should watch a serbian film
