Ever watched the movie "The butterfly effect"?
The main character of the movie is basically a time anomaly who shouldn't exist, the whole film is a metaphor for him being the flap of the butterfly's wings, and the theatrical ending implies he's just some random sap strung into a series of events, while the alternate "directors" ending with the umbilical cord implies that he's something more than that, his entire existence is a complete and utter anomaly, everyone he knows and everything he touches goes wrong for himself or those he cares about simply because he's not supposed to exist in the first place, he is completely out of sync with reality and what is "supposed" to be to the point that every little action he takes tears a crossroads into existence.
He learns in the end that there is no negotiating with this power he has and that no matter what ending he tries to write for himself, it'll always hurt someone else, so instead of attempting to exist, attempting to find the least damaging path, some path that doesn't leave damage, he decides to never play the game, to never "flap" his wings and come into existence as a butterfly, because in the end his harmless little existence, his "miraculous" birth, his mom holding him in her arms, all of that love and desperation will eventually lead to pain and death.
He stops the hurricane by killing his own existence, he was born out of a time anomaly, he dies from a time anomaly, and nobody ever knows the passion, love, and determination he went through because the fact they never heard of him is a testament to how much he loved all of them.
It is also hinted that all his previous siblings who were also stillborn babies had the same time-travel powers and reached the conclusion that killing themselves was the best decision they could make. Hence why the protagonist is referred to as a miracle child.
TL DR: In the director's cut ending of the movie, he travels back in time so he can kill himself inside his mother's womb by strangling himself with the umbilical cord, resulting in a stillborn birth.
