It's a party trick that will cause everyone to run screaming for the exits.

In this spine-tingling clip, an actor collapses to the ground and transforms himself into a creature resembling a cross between a spider and the girl from the Exorcist, according to Daily Mail.

He manages to move his body into positions unimaginable for the ordinary person.

The jerky movements, combined with the thuds on the ground as he moves across the floor, makes the short clip seem like something out of a horror film.

The "creature" then collapses onto the ground, seemingly waiting to attack its next prey.

The footage was first uploaded to Instagram where it has been viewed tens of thousands of times.

Only1dara replied: "Thx for the nightmares. Well done"

Kelanich said: "He's like an octopus in human skin"

Instagram user asked why the newest Alien monster was CGI when there were men like this around.

The man behind the contortions is American actor Troy James.

He has appeared in the indie horror film the Void, as we the US vampire series the Strain.
A similar creepy spider walk is seen in the horror classic the Exorcist.
