I'm looking for two separate Japanese found footage / ghost video clips that I saw in YouTube horror compilations around 2015–2017, but origins of them may be older. These compilations were similar in style to the ones posted by channels like alotofmusic — numbered collections of creepy low quality Japanese clips (often reuploads of originals) that have since been mostly removed by YouTube. I believe both clips were independent short found footage films that ended up mixed into supernatural compilations alongside more typical ghost/paranormal clips.

Clip 1: Couple finds a mutilated body in a bathroom

• Setting: Daytime, overcast but bright weather. A city in Japan.
• Characters: A young man and woman, walking around the city and talking. Their faces are pixelated/blurry (mosaic censor effect), and their voices are distorted to a high-pitched tone.
• Plot: They appear to be heading to or returning to an apartment. They enter the apartment and seem to be looking for the owner/resident. After some time searching, the woman screams and runs out of a room, then out of the apartment entirely. The man goes silent and keeps filming. He enters the room she ran from — what appears to be a bathroom — and finds a bloodied, heavily mutilated body in the bathtub. The body is extremely detailed and realistic. Flies appear to be flying around it. He films the body for a while, and then the video ends.
• Atmosphere: There is a supernatural element present, though I don't remember exactly how it manifests. It's not pure gore/splatter — it has a paranormal undertone.
• Style: Amateur handheld camera, very raw found footage feel. Duration approximately 5–8 minutes.

Clip 2: Man drugs woman on a date, she becomes possessed

• Setting: Night time, inside an apartment.
• Characters: A man and a woman (possibly wearing a black dress). Their eyes are covered with black bars (not pixelated — a solid black censor strip across the eyes).
• Plot: It plays out like a date at first. However, the man is clearly spiking/drugging the woman's drink. After a while, the woman passes out. The man films her while she's unconscious, then leaves to another room. From the bedroom, a continuous, unbroken moaning/groaning sound begins. The man returns to the bedroom and finds the woman standing with her head thrown back, howling/wailing — as if something has possessed her. I don't remember exactly what happens next, but the man somehow manages to lay her back down. Then, as he shifts the camera, a paranormal figure comes into frame — and the camera glitches with black squares and freezes on a single final frame, ending the video.
• Style: Found footage, handheld camera.

Any leads — channel names, video titles, timestamps, similar compilations, or even vaguely similar clips — would be hugely appreciated. Thank you!
