You can always rely on social media to show you something you don't see every day—in this case, it's an unusual pet interrupting his owner's nap.

In a viral video that has 17.8 million views on TikTok, a woman can be seen lying on the sofa before she is rudely disturbed by her sheep, called Rambo. The name appears to be fitting as he is ramming his head into hers in a desperate bid to make sure she stays awake.

The video shared to an account dedicated to the animal @ramalambadingdong4 has received more than 343,000 likes since it was shared on June 2.

At the time of writing, the video captioned "#headbutter" had received almost 12,000 comments.

"Get a lamb as a pet they said... it's cute they said... 6 hours at A&E later," said one user.

Another wrote: 'WAKE UUUPPPPP MUM!'

A third commenter asked: "Is this your personal alarm?"

While many people including the owner can see the funny side, one worried user pointed out that headbutting can lead to an internal head bleed. Indeed, scientists have previously found evidence that horned animals can suffer from head injuries.

Newsweek previously reported on a study published in the journal Acta Neuropathologica challenging the widely held belief that ramming animals do not experience brain injuries. It supports the idea that studying animals with brains evolutionarily similar to humans may aid researchers in understanding and mitigating traumatic brain injuries.

"Our lab tries to use evolution to help solve medical mysteries," wrote Patrick R. Hof, professor of neuroscience at Icahn Mount Sinai and senior author of the study. Traumatic brain injury (TBI) research often relies on smooth rodent brains, which may not be the best ones to use. Therefore, the team studied the brains of ramming bovids, expecting better insights into human TBI.

Initially, the animals' brains appeared healthy, with scans showing intact structures. The researchers then sliced the brains and treated them with antibodies to detect phosphorylated tau proteins, markers of TBI and Alzheimer's disease.

Microscopic examination revealed significant staining in muskoxen brains, indicating TBI-like damage, while bighorn sheep brains showed only light staining. This suggested that muskoxen brains sustain chronic, repetitive damage similar to that seen in TBI patients.

The front part of the muskoxen's brains had a lot of tangled tau proteins, which is a pattern also seen in a brain condition called chronic traumatic encephalopathy (CTE). Interestingly, an old female muskox had much more of these tangles than an older male and another female, which was surprising because males usually ram into each other harder and more often.
