Well, if you wanted a hair-raising horror flick; you got it.

He wrote: "I’d say tonight was pretty damn eventful! @RobbieBanfitch you’re amazing, hilarious, and this rewatch of

@TheOutwaters has solidified my opinion that I believe this to have one of the most horrific and traumatising sequences i’ve ever experienced in a found footage horror film."

Another said: "I'm still processing #TheOutwaters. I am not sure if it worked for me. The sounding made me so uncomfortably dizzy that I had to leave the theatre to vomit. This never happened to me before. It's more disturbing than scary if that makes any sense."

While a third shared: "It was disorienting, disturbing, extremely anxiety-inducing, and an absolute journey into hell."

The film was written, directed, and stars Robbie Banfitch.

It's presented through found footage from memory cards belonging to friends who venture into the Mojave Desert to shoot a music video, where they encounter mysterious and threatening phenomena.

But aside from its shocking, visceral audience reaction, the horror has received positive reviews from critics and even scored 72 per cent on the movie website Rotten Tomatoes.

He added: "When it’s working, The Outwaters feels like the audience has been invited to witness the horrors running through Mike’s head at the end of The Blair Witch Project as he stares into the corner in the basement."

He said: "A stunning embrace of abject horror that peels back the layers of skin just as it does those of the mind, The Outwaters stumbles upon a brutal brilliance in the desolation of the desert."

I think I'm definitely going to have my peppermint tea close by for this one.
