It is called "Sacred Nasal Geometry".
Now, as a creator of rather ... I donno... "strange" pix, I often get that loathsome, and I mean LOATHSOME question "what does it mean?".
And fuck me people are pushy about wanting an explanation. The more polite I am about declining, the pushier they get.
So in the interest of explaining every goddamn picture I've ever made and will make, here's a wee insight into "Sacred Nasal Geometry".
The pikkie is a pisstake. Sacred Geometry is an occult concept (wiki article here), and occultists take a lot of baloney very seriously, because they read meaning into things. So here, a woman's nosebleed is in fact seen as an important thing to be measured and quantified and studied for exact meaning. It's not just blood, this means something and has significance.
Yet its just a nosebleed, and the study thereof has made it both important and utter bollocks.
We as humans (not just occultists) have this ridiculous need to understand everything around us, to find meaning in everything, including life - and I could digress here, but let's skip it. Actually no, here have some insight: Life has no meaning, you're welcome, move on.
This need to "know", "understand" "to find meaning" is exactly what is portrayed here. Therefore, this picture is taking the piss out of YOU, the viewer. You wanna know what this mysterious picture means, but it's literally just a mystery. It's a mirror, showing you your search for understanding the image you are looking at.
Mystery novels/ films are more fun until the killer is revealed. Bigfoot is exciting as a mystery and prevails despite debunking because we don't really wanna know, we just want a good, creepy mystery to baffle over.
Mystics understand they can never know their God, but they appreciate the mystery of not knowing and the wanting to know - without ever finding an (exact) answer.
And this is what this picture is - a mystery, nothing more, but also a pisstake of your quest for meaning, for meaning in this picture.
On the other hand, it could just be some clever application of principles of design/ Gestalt psychology ( wiki article here ).
So once and for all, stop bloody asking.
