It causes strong emotional fluctuations, especially fear and anxiety, and needs to be treated with caution. These experiences may have a profound impact on people's mental state. It is recommended to try in a safe and controlled environment and avoid long-term indulgence. The following are some possible methods for reference： --- ### 【Psychological Suggestion and Thinking Experiment】 1. **The abyss of self-dialogue** -When I was alone late at night, I repeatedly asked myself: “If this is the last day of my life, what is my biggest regret?" "Or “What if my life choices are all wrong, what should I do?" ”This kind of questioning of the meaning of existence may trigger deep unease. 2. **Blurring the boundary between fiction and reality** -Try to record dreams in detail for a week in a row, and deliberately confuse the details of the dreams with the real memories. When you start to wonder “whether a certain scene has really happened”, the sense of cognitive uncertainty will spread. 3. **Assume extreme situations** -Imagine suddenly losing all social relationships (family and friends disappear), losing control of your body (such as gradual blindness), or time cycling (repeating the same day but unable to change the ending). This kind of thinking experiment will expose human beings' primitive fear of getting out of control. --- ###【Deliberate design of senses and environment】 4. **Sensory deprivation and overload** -**Hearing**: Playing low-frequency noise (such as submarine sonar or infrasound before an earthquake) in an absolutely dark room, this kind of sound can trigger instinctive alertness； -**Vision**: Staring at the ”Valley of Terror" image (such as the weird smile of a real-life doll) or the infinitely reflected surface triggers non-human fear in the subconscious. 5. **Sense of space oppression** -Enter the abandoned building alone (to ensure physical safety), pay attention to the sound of rusty door shafts, the smell of dust and sudden temperature changes. Human vigilance to the decaying environment stems from the instinctive avoidance of “dangerous territory” in evolution. 6. **Liminal Space (Liminal Space)** -Going to empty hospital corridors, unfinished shopping malls, or faded old-fashioned amusement parks in the early hours of the morning, these scenes of “neither functional space nor pure ruins” can cause a weird sense of stagnation in time. --- ###【Deep trigger of Culture and Symbols】 7. **Touch taboo narratives** -Read the description of “the indescribable” in the “Cthulhu Myth”, or study the concept of "the indescribable God" in religion, and take advantage of the human instinct of awe of the unknown. 8. **Alienation of body perception** -Look at yourself in the mirror for a long time until your face becomes unfamiliar (the Texler vanishing effect), or try to describe your movements in the third person (such as “This right hand is picking up a water cup”) to create a sense of self-alienation. 9. **Participate in ritualized behavior** -Design a set of meaningless private rituals (such as having to tap the door frame three times with your left hand to enter and exit the room). When you deliberately break it one day, you will feel the absurd anxiety of violating your own rules. --- ###【Pay attention to risks and Suggestions】 -**Psychological safety valve**: Pre-set termination signal (such as specific music or items), stop immediately when you are unwell； -**Reality anchor point**: After the end, perform sensory "restarts” (such as washing your face with cold water and touching a rough blanket), and return to the present through physical stimulation.； -**Avoid long-term triggers**: Fear experience consumes a lot of mental energy, and frequent attempts may lead to numbness or generalization of anxiety； -**Artistic alternative**: Through the creation of horror-themed stories, paintings or music, emotions are indirectly transformed rather than directly immersed. --- In the end, human emotional complexity often stems from resistance and curiosity about “out of control”. If you want to enhance your emotional perception, perhaps exploring love, compassion, or transcendent experiences (such as the sublime sense of nature) is a more sustainable direction. True deep emotions do not necessarily have to come at the cost of fear.
