Startling footage has emerged of a woman crawling along a Baltimore street and up walls while on a drug-induced high which mimicked an exorcism.

The woman was filmed writhing around barefoot on the street, her legs and arms covered in dirt, while passers-by taunted her from behind their cell phones.

They labeled her a 'zombie' and likened her state to an exorcism, laughing and imitating her screams.

Neither Baltimore City nor Baltimore County Police was unaware of the footage or anything similar to it. It is not known what became of the woman or what substances she took to send her in to the frightening state.

The video was taken on Saturday and shared online the following day. Viewers said she appeared as though she was reenacting the zombie film 28 Days Later.

As she stumbled along the street, the onlooker goaded her to twerk and show off her 'butt cheeks' before labeling her 'ugly a**'.

She fell in to the porch of another onlooker who sat on his steps as she struggled to keep her balance.

'Help me!' she squealed after propping herself up on to wall.

The woman from behind the camera yelled back: 'Ain't nobody helping you, you dirty as s***'.
