Footage of a fetus visibly moving inside a mother's abdomen has gone viral (video below).
In the video, originally posted to YouTube in 2016, a woman's unborn baby appears to almost break through her abdomen while it repositions itself. The video collected over 36,000 views in just over a year, with some commenters referring to the footage as "creepy" and "disgusting."
According to Live Science, in the last trimester of pregnancy the baby moves into position to descend to the vaginal opening in what is referred to as "the drop." The baby will turn itself around to place itself in the perfect position for the mother to give birth.
When The Shred reposted the video on Oct. 15, it quickly picked up over 700 reactions and over 125 shares in 72 hours.
"Damn, I think I'm going to faint," said one user. "Makes me feel queasy watching it. I still find it amazing a human body inside a human body. Every time I've been asked to feel my tummy the baby's kicking I start getting all wimbly wambly wombly and cross eyed like my lights are about to go out. I have to start doing deep breathing exercises. I just don't know how you ladies do it. Amazing."
Another Facebook user said she was confused about why the video was drawing such strong reactions: "I think the power of Facebook blows things out of proportion ... it's a baby obviously close to due date moving in an ever decreasing space, get a grip people! It's all completely normal ... no horror involved. When I was pregnant with my daughter I saw knees, elbows, hands and feet towards the end of term."
Another user echoed that confusion: "Why do some people consider the movement of the baby as like something out of a horror movie? It is beautiful; a new life about to evolve."
A University of Texas at Dallas study attempted to investigate exactly what causes videos to go viral. According to The New York Times, the study examined the reactions of 256 participants who were shown videos and then had their emotional responses measured along with their desire to share the videos.
The UT study found that users were eager to share videos that gave them an intense emotional response, whether the emotions were positive or negative.
Another study by professors at the University of Pennsylvania found that people were more likely to share stories they found uplifting than depressing.
