Level 667

Level 667 is the 668th level of the Backrooms, and is widely considered to be one of the most dangerous and claustrophobic levels that reside within the confines of The Backrooms.
==General Description==
Level 667, colloquially known as Disquieting Claustrophobia, is an enclosed and extremely claustrophobic complex of interconnected passages, with the architecture resembling that of a series of vents. The level's size is approximately 300,000 square miles. The atmospheric differences of this level vary greatly from person to person; a wanderer reported that the vent was freezing in a journal; said wanderer died in the vent. Mysteriously, the corpses of each wanderer seems to be "swallowed" into the murky and slippery surface. Holes in the seemingly hardened walls are frequently found here. However, these holes display a place that no wanderer even thinks of during their worthless lifetime. However, it was heavily disputed for a short amount of time that these holes led to different levels such as Level -69; seeming to be at completely random frequencies and locations. The weather in this level can not be visually observed, but rather audibly. Wanderers reported the sounds of thunderstorms and other various types of weather, including blizzards.
Entities in this level seems to be exterminated from this level entirely due to the claustrophobic like paths that Level 667 seems to just generate with no guaranteeing purpose; scientists have hypothesized that Level 667 has an extremely ominous anomaly that involves this level seeming to randomly generate the passages, each passage varying greatly in it's design. Some passages can be reasonably large with the ability to be able to sit on one's knees; other passages gift extremely tight passages that are particularly tedious to crawl through. Due to this, Level 667 is known for posing extreme environmental hazards, including being lodged in passages without being able to successfully execute their escape, and even some reports of wanderers being halted by their advances by complete cave-ins, forcing wanderers to backtrack and turn down another passage. Extreme temperatures have been observed up to 49 degrees Celsius. Wanderers in these "heatwave" like scenarios are extremely vulnerable to heat-strokes and comas.
An extremely faint mist hangs around this level, unaffected by the sometimes extreme temperatures. The cause of this mist is currently unknown, however it is assumed that it is caused by some conflict between hot and cold air in the passages. However, this is purely just a rough hypothesizes. Wanderers and scientists have often commented on a puny smell; this smell does not vary greatly, staying consistently to a smell of "rotten lemons". Personal belongings can be rarely found, such as clothing, mobile phones, and other gadgets. However, cellular devices prove fruitless; in fact, all gadgets prove unreliable and walkie talkies and radios are often audibly distorted to the human ear. This hazard poses a severe risk of no help when needed; wanderers will have to purely rely on each other if entered with more then one person. Lights in this level often flicker; there is no light anywhere in the vent to potentially assist with a wanderers sight. Flashlights, as aforementioned, often flicker and can even go out entirely. Due to this, light sources according to experienced wanderers prove difficult to properly function. 
Questionable writing can sometimes be found deep within the passages of Level 667. These notes can range from simple notes such as tally marks to even satanic symbols and pentagrams. The writing appears to be written with a thick, red substance, thicker then the human blood. Touching this substance can cause severe illness on any wanderer, regardless of their strength and immunity to sicknesses. Whether or not this writing was actually written by a wanderer is unknown. Various drawings can also be commonly found, including "family drawings"; this suggests that even children have entered this level for unknown reasons.
Sound is incredibly altered within the passages of Level 667. Wanderers are heavily affected in varying ways, the most common reports being that all sound being muted or dampened. Sound is altered to an extent that there is zero reverb throughout the level. This is due to the space being claustrophobic to the point that sound cannot travel beyond the level's confines. However, there is often reports of a faint echo that reverberates throughout the entire level; this is commonly attributed to severe anxiety and severe panic attacks; wanderers are commonly affected mentally due to this echo for unknown reasons.
Level 667 has extremely rare occurrences of it's architecture entirely shifting. This commonly takes wanderers to that said level with that said architecture. Even though it proves to be some form of escape, it is unadvised to crawl to far into the level, as this event is commonly associated with wanderers going extremely far into the level's strict confines.
==Entities==
Due to the nature of Level 667 being claustrophobic enough in some passages to the point that an adult cannot fit, entities theoretically cannot stand the environmental nature of Level 667. The nature of this level makes colonies or outposts infeasible. Wanderers have heavily disputed that entities have existed within the earliest periods of this level; scientists debunked this theory, stating that entities and the environmental hazards themselves "do not mix".
In addition, they displayed a diagram of the level itself very recently; It consisted of a 3D diagram of the entire level, with different areas with larger expansions and smaller pinches. Due to this, wanderers took to Reddit and published this diagram; to this day, no further expansion on the theories of this diagram and how it was even drawn has been added, and most likely never will due to the claustrophobic level's environmental nature.
==Entrances and Exits==
===Entrances===
*The only way to enter this level is through tight passageways in Level 427.
===Exits=== 
*The only way to escape this level is by finding an abnormally colored wall. Banging your fist on it upwards of 500 times has a very small chance to lead you to Level 3 or Level 213. It is worth noting that the amount of times one has to bang their fist on said wall is very inconsistent, and can take presumably 5 million times at maximum quantity.
*It is rumored that managing to squeeze oneself through the countless holes may lead one to The Void. This method is heavily discouraged.
 
A log? I wonder who wrote this...
I am typing this as to share this full experience, and to potentially say my last goodbyes to my wonderful family.. I woke up, with a sense of dread and anguish for some reason filling my consciousness. I readjusted my gaze, sweeping my vision across the enclosed landscape. I had a sense of severe claustrophobia.. I look up. Shit. I have to escape this area. This place is just stupid. Crawling, I took into account that the tunnels were dirty as fuck. There was writing to my right, and to my left.. a hole? I put my face into the hole and stick my head out to look. Nothing but an evasive void. Still, I had to get my head out to explore more of this shithole. I get my head out.
I continue to scan the area as I try to inch my way through these shitty tunnels. This looked oddly familiar; like a vent system I was trying to crawl through.. but to where? How was this even made? It's just in the middle of a fucking void.. Well, I had to find a way out. I inch further. A turn... yes! I turn it. My heart explodes out of utter fear. A cave in.. There's no other turns..! Well, I'm sitting here, typing this on my phone, as if anybody finds me here.. Well, farewell everyone, it was fucking worthless to end up in The Backrooms anyway.
A light... A way out...
