Most 'realistic' depiction of a dream is scarily accurate

The dream simulation created by filmmaker Steal Adcock has 'terrified' some viewers.

Ever woken up and been certain you were just in the middle of experiencing a dream, but aren't for the life of you able to remember any it?

Well, you're in luck - or not, depending on how you feel about the video below. Warning: Contains footage some may find distressing:

Steal Adcock produces simulation videos on his YouTube channel 'HandintheBoxInc' and there's one video in particular which viewers believe is eerily 'accurate'.

The dreamer is played by Adcock himself and sees him begin in the bathroom.

While this may seem a normal enough setting, sadly, it all descends from here, Adcock making his way into 'a pit of darkness', finding himself in a forest and later, a tunnel.

Also introduced at moments throughout the dream is a random girl named Jayda who - one moment - is tied up by police tape and - the next - is traveling upside-down on a moving wheelchair.

Despite the random nature of the simulation, people are saying that it 'captures the cluttered, almost claustrophobic nature of dreams'.

"Every time I think of the dreams I had I always feel they're claustrophobic, and this emulates it pretty damn well. Good job," one viewer commented.

Another added: "Bro this is super realistic, I didn't even think anyone could reproduce what its actually like to be in a dream."

A third commented: "Can totally relate my dream to this video. The way it moves from one scene to another skipping few moments. It is really beautiful and scary version of dream. Nice work."

While someone else also said: "I was laughing for the first few seconds because I never really knew how others experienced dreams but this is quite literally a perfect example of how I experience them.

"Just jumping from one thing to another, everything confusing as hell when I try to recall what happened after I wake up. Super entertaining."

However, not everyone who watched the simulation seemed to to agree with its realism.

One person wrote: "Bruhhhh if ur dreams r like dat I wouldn't even go to sleep lmaoo [sic]."

Another added: "This is terrifying, who's dream is this?!"

"That’s not a dream that’s a nightmare," someone else penned.

Well according to sleep researcher J. Allan Hobson, there are five basic characteristics of a typical dream, which seem to fit in line with Adcock's simulation.

The five characteristics - outlined in his his 1988 book, ​The Dreaming Brain - are as follows:

1. Dreams often feature intense emotions.
2. Dreams are frequently disorganized and illogical.
3. Strange dream content is accepted without question.
4. People often experience bizarre sensations.
5. Dreams are difficult to remember.
