About Mental Space
SON：
Hey! Have you been in Thailand lately?
I wanted to ask you something—I instinctively felt you might know about this.
So, I’ve been attending some body-movement workshops lately, with ritual-like activities—group trembling, vocalizations, and everyone can shift between being a leader or follower. After three sessions, I noticed a pattern: when there are over five people, intense focus and altered breathing trigger synesthesia. When I close my eyes, colors shift, spaces emerge—it’s wild! The first time, I saw abstract grassy waves rolling with the music; the second, a spiraling “sun hole” like a navel; today, it was a sapphire-blue pentagon. Even weirder, I could “observe” these visuals as if detached—turning my head showed things behind me, beyond imagination. It’s not just imagery; it’s another dimension.
I’ve mentioned it to others, but they don’t quite get it. I even sketched a mind map trying to process it. What’s happening? These endogenous images must have a mechanism, right? It feels tied to breath, not just meditation!）

Hi！你最近是不是在泰国～
我来问问个情况，就是下意识感觉你会知道点什么
是这样的 最近有参加一些身体运动向的工作坊，有一些游戏形式会比较偏ritual的状态，集体震颤身体，包括发声等等，每个人会都随时可以成为leader or follower。我已经遇到过三回了，发现一些规律，就是在超过5个人的时候，很集中精神去行动，呼吸改变之后会有通感。闭起眼睛会有颜色变化还有有空间。说实话有点吓一跳，第一次看见的是抽象的草坪 会有草地的波浪滚动 跟着音乐深浅都会变，第二次是肚脐眼一样转进去的太阳孔，今天看到的是宝蓝色的五边形，而且闭起眼睛看是可以成为observer的的甚至我慢慢转头转身都可以看到后脑勺背后也还有一片东西。 和 imagery 无关了，是另一个方向。
我有简单和身边的人提起过 但感觉好像大家不太能get 到，我甚至最近想着想着还画了思维导图。
这个到底是怎么回事呢 感觉到这种 endogenous image 的生成应该是有方法的吧 但感觉又不是冥想 隐约觉得和呼吸很相关！
SUN：
Hi Yiyang! So glad to hear from you.
Mechanically, this isn’t too complex: your visual cortex doesn’t require external stimuli to activate. Sensory deprivation—like dark retreats—often triggers vivid inner visuals (people even see full “light worlds” after days in darkness, needing anchors to stay sane). Float tanks can blur reality’s edges too. Your ritual-induced trance is fascinating—collective movement, rhythm, sound, and a relaxed-yet-alert state align with shamanic practices.
阳：
hi逸阳！收到你的消息真高兴。
这个东西mechanical地来讲并不复杂，就是你的视觉皮层并不一定需要外来视觉信号才能激活，要去激活它就有各种各样的方法，比如感官剥夺就是一种，闭黑关很多天的人很多都会在后期看到一个完整的光明世界，这时候反而需要一些标的物来确保自己的sanity。有些人在类似漂浮仓疗法里面也有这种情况，会分不清所谓“现实”和自造的边界。你讲到的这个情况就更有意思一点，似乎是在仪式中进入了trance，这也是很常见的一类触发方式，相信你可能也联想到了类似萨满的操作：集体行动、身体、声音、重复的节奏，放松但警觉的参与。
SON：
Maybe it’s because I’ve been isolated lately—working on animations alone, days without speaking, feeling my body dissolve. Plus, winter here means 3-hour daylight… now recovering slowly.
“Relaxed yet alert”—that’s the key!
孙：
可能是因为这里有时候太闭世了 就是在自己做动画 偶尔一天不讲话会感觉现实和肉体消失了[脸红] 而且这里冬天又是长夜 白天只有三小时 现在慢慢恢复过来一点了。
放松但警觉 这个关键词太对了！
SUN：
Another note: your strong visual aptitude (maybe linked to animation work) amplifies this. While mechanics explain it, an animistic framework might feel safer or more complete—this could involve possession or interaction with external forces/spirits. It raises questions: What is the “self”? What’s being penetrated or influenced?
Anyway, stay cautious. Interrogating your boundaries is wise—we don’t want random forces hijacking you, right?
阳：
我觉得还有一部分值得注意，你的视觉能力本来就很强，这和你投入于动画创作可能是互为因果。虽然这些东西可以用机械的方式来解释，但是放在万物有灵的体系里来处理可能更完整也更安全。这就涉及到可能的possess 或者至少是与其他forces甚至spirit的交互。这还会涉及到“自我”是什么，被穿透、影响和占据的是什么…
anyway 留个心眼 注意安全 适当的时候去拷问自我的边界可能是有必要的，我们不希望被随便什么乱七八糟的东西给操纵，对吧。
