I asked ChatGPT about the person who stared at me from around 2 a.m. to 4 a.m. in the middle of the night. Top-tier model ChatGPT o3: “Most likely: antisocial personality disorder + sadistic tendencies (dark tetrad) — meets all four points of coldness, cruelty, manipulation, planning, and control over others”

I had a similar experience in my late twenties, too. (What I experienced felt far creepier than the video above.)
There was someone who stared at me blankly from around 2 a.m. to 4 a.m., and there were also other events that could only be called abnormal, along with intense feelings of anxiety and fear. It still feels strange to me, so I asked ChatGPT about it.
I’m going to ask ChatGPT, so please take a look at the exchange.
What are the symptoms? mentioned in this video?
A younger sister suddenly glares at her older sister at 3 a.m. The older sister wakes up sensing something is wrong and finds her younger sister staring at her without moving a muscle. At first she thought it was just fooling around, but she gradually became frightened. The sister, who never blinked, kept a blank expression and shed only tears. When their mother called out to her, the younger sister supposedly fell asleep again as if nothing had happened. The older sister was traumatized by her younger sister. (AI-generated transcription)
The younger sister’s behavior in the episode from this video—suddenly glaring at her older sister expressionlessly at 3 a.m., not blinking, shedding tears, and then sleeping as if nothing happened when their mother called out—may indicate the following medical or psychological symptoms:
Possible symptoms or conditions: 1. Night terrors A type of sleep disorder commonly seen in children. The person may suddenly scream during sleep or open their eyes wide with a frightened expression, but often has no memory of it. Even if they seem awake, they may actually be in deep sleep and unable to hear other people’s voices. 2. Sleepwalking An abnormal behavior that occurs during deep non-REM sleep. They may look awake with their eyes open, but in reality they are not conscious. They may stare at others or walk around, but have no memory of it the next morning. 3. Epilepsy (especially complex partial seizures) Blank expressions, tears, and unresponsive staring can appear in mild epileptic seizures. Nighttime seizures in children in particular can easily be overlooked.
The older sister’s traumatized reaction This is a very typical case of “someone who witnesses night terrors or sleepwalking and feels intense fear,” and for witnesses it often becomes a horror-like experience.
For example, you wake up around 2 a.m. and the other person, still in bed with their chin tilted upward—in other words, from your side, their face appears upside down—has their eyes wide open and is staring blankly at you. If you ask, “What are you looking at?” they don’t respond. But if you wake up the person beside you and say, “This person keeps staring at me; something’s weird,” then as soon as the other person wakes up, the staring stops instantly and they go back to sleep as if nothing happened. So only the person who woke up—in this case, only me—saw the abnormality, and the others did not. The person says they don’t know anything about it. What does this mean? There was also another similar scene, and that staring person was someone who had killed small animals and also tried to kill a dog.
