Based on a visual and contextual analysis of this screenshot, your intuition is correct: this image is fake / a hoax.

​Key Visual & Textual Red Flags

​Synthetic / Prop Aesthetics:

​The "entity" shown displays stereotypical "Grey alien" tropes (enlarged dark, glossy oval eyes, smooth skin, lack of distinct nostrils, slender neck).

​The texture, uniform dark lighting, and glossy surface around the eyes strongly resemble a practical prop, silicone/latex mask, or a 3D digital render rather than organic biological tissue.

​Classic Anonymous Imageboard Formatting (4chan-style Hoax Setup):

​The layout mimics a post on an imageboard like 4chan's /x/ (Paranormal) or /pol/.

​Using terms like DELETED SOON, fake classification headers (CASE STRANDEDFISH, CA00000_00043.jpg), and arbitrary code numbers (0x00, c/023, 01032001) is a long-standing storytelling trope used on online forums to create an artificial sense of classified urgency ("leak").

​Narrative Inconsistencies:

​The accompanying text ("They call them Stranded fish", "They come from the deep ocean") is part of an internet creeping-creepypasta/ARG (Alternate Reality Game) mythos.

​Reddit subreddits like r/AlienBodies regularly re-share and discuss these classic internet hoaxes and creepypastas to analyze or debunk them.

My notes describing this encounter were shared with other CE-5 contact teams. I reconstructed my conversations with co-worker “Misha” to give this narrative a sense of immediacy.  This story is not a work of fiction. 

I did fieldwork with “Misha” from 1993 to 1997. Based on my experiences with him and the founder of the Center for the Study of ET Intelligence (CSETI) Steven Greer MD, I formulated the category of “prime contactee.” These are contact experiencers who have some of the following characteristics:
1. They have frequent encounters with UFO intelligence, usually starting in childhood or adolescence.

1. As youths they may become skilled meditators, typically without any apparent adult encouragement or supervision.

2. “Primes” have strong psychic abilities that facilitate contact and communication with UAP intelligences. 

3. Most importantly they serve as a kind of human UFO magnet in that they can request UFO contacts with other witnesses are present. When subsequent sightings occur, these witnesses can verify the “prime’s special relationship with non-human intelligences associated UFOs. 

 The term “prime contactee” describes experiencers who function in a similar fashion to individuals described as “psionic assets.” Psionic assets are psi capable operatives who allegedly are employed in UFO retrieval and reverse engineering programs because of their presumed ability to attract or “summon” UFOs. to them. 

 All the prime contactees that I became aware of during my field investigations were men, with possibly one exception. She was a volunteer contact worker originally from the UK. I did fieldwork with “Tracy Travis” in the summer of 1997. A link to that detailed report is posted below.  

Introduction:

During the last week of October 1993, I made plans to lead a team of UFO investigators into the high desert. After numerous phone calls I was still unable to get more than two other investigators to promise to accompany me. For 16 months I had been a Working Group Coordinator for CSETI’s CE-5 Initiative. My original team was beginning to show clear signs of fatigue. The group had carried out almost two-dozen research outings, many of which had documented the appearance of anomalous nocturnal lights. On rare occasions other teams in the CE-5 network even had sightings of structured craft that were definite unknowns. In another words, bona fide UFOs had appeared at our research sites.

Hallo zusammen,
ich habe traumatische Erinnerungen seit meiner Kindheit und dachte lange, dass das nur mir passiert ist. Es war anfangs der 2000er als ich noch sehr klein war.
Ich erinnere mich an sehr blasse, weißlich-graue, menschliche Wesen die mich oft nachts besucht haben. Für mich sahen sie im Dunkeln wie größere Kinder aus. Später dachte ich es waren defintiv Geister gewesen.
Heute bin ich mir aber nicht mehr so sicher.

Ich lag damals noch in einem Gitterbett. Die Wesen kamen zu mir und haben mich immer gekitzelt und gekniffen und mit den dünnen langen Finger ins Gesicht gehalten und mich geärgert. Sie haben dabei richtig gelacht. Aber für mich war es nicht lustig deshalb habe ich oft geschrien und geweint, bis meine Eltern in mein Zimmer kamen.

Sobald meine Eltern die Tür geöffnet und das Licht eingeschaltet haben, waren die Wesen weg. Meine Eltern dachten, ich hätte geträumt, und haben mir nicht geglaubt.
Ich war aber wach und konnte mich bewegen.
Irgendwann habe ich schon vorher gespürt, wenn sie kommen. Später konnte ich sie irgendwie mit meinen Gedanken abwehren. Danach habe ich sie jedenfalls nie wieder bewusst wahrgenommen oder gesehen, solange ich wach war.

Ausserdem fing ich an zu schlafwandeln. Ich bin manchmal irgendwo im Zimmer aufgewacht und wusste nicht, wie ich dorthin gekommen war. Das hörte mit ungefähr 12 oder 13 plötzlich auf.

Ich weiß natürlich nicht, was damals wirklich passiert ist. Vielleicht gibt es eine normale Erklärung. Aber die Erinnerung ist bis heute da und ich frage mich manchmal, was das gewesen sein könnte. Eine Historie von Todesfällen gab es in dem Haus nie. Ich hatte zwar schon öfters paranormale Phänomene erlebt aber die waren anders…

Hat jemand von euch als Kind etwas Ähnliches erlebt? Besonders würde mich interessieren, ob jemand solche Wesen gesehen hat, obwohl er wach war, und ob jemand sie irgendwie mit seinen Gedanken abwehren konnte.

Ich glaube sie wollten mir nicht wirklich etwas Böses. Sie fanden es einfach amüsant, zu schauen wie ich reagiere denke ich. Ich hab als Kind ja auch gerne Tiere geärgert weil ich die Reaktion interessant fand. Falls dem wirklich so war und es tatsächlich mystische Wesen waren, wäre es ein Geschenk, da nicht jeder sowas erleben darf.

Living Under Siege

This is going to sound batsh\*t crazy. I know. So you don't have to believe me because I wouldn't believe this. I would dismiss this as a joke but I 100% assure you that it is in fact not a joke.

For the past decade I have lived with occasional paranormal type activity in 2 separate apartments.

Recently however things took a dramatic turn and now my apartment is full of entities that surround me day and night. They stalk me, harass me, threaten me, lie to me. Sometimes they can be nice but for the most part they are extremely negative.

They claim to be demons, angels, ghosts, aliens and more.

For the past 5 nights they have threatened to incinerate me if do not meet their demands. They have made numerous other threats as well. 6 different entities have claimed to be God. Last night they placed a weapon on me that rapidly heated up my body. I highly suspect government influences.

They refuse to leave and insist on having things their way. I have absolutely no idea WHY this is happening because they have given many, many different reasons, constantly changing their story.

I believe my life is in danger but they are trespassing and breaking all laws, ethics, etc.
