由Z世代代表人物、部电2005年出生的建议导演凯恩·帕森斯（Kane Pixels）执导的《后室》（Backrooms），原本被视为一部带有Cult色彩的独自小众独立电影，却意外实现了票房与口碑的部电双丰收。这部成本仅1000万美元的建议影片，全球累计票房已飙升至3.29亿美元，独自并于6月26日在中国大陆正式公映。部电

这一现象级成功背后，建议折射出Z世代（以2005年出生者为典型代表）的独自趣味、焦虑、部电压抑与妄想，建议已突破世代界限，独自演变为当代人的部电集体共识。换言之，建议不仅是独自“后室”，整个世界都潜藏着成为“阈限空间”（Liminal Space）的可能。

开篇或许有些危言耸听，但事实上，我沉迷于《后室》的场景设定而非剧情，并非因为刻意迎合Z世代标签，也未联想到“梦核”（Dreamcore）、“怪核”（Weirdcore）、“池核”（Poolcore）或“赛博乡愁”（Cyber Nostalgia）等流行术语。

早在日本漫画家大友克洋的《童梦》和《阿基拉》中，便已出现类似梦核的场景。然而，那时的审美与叙事迅速从“梦境”滑向“硬核”（Hardcore），走向极致、颠覆乃至失控。相比之下，“梦核”相对安全且稳定。在《后室》中，若保持适度的好奇心，它本身是一个相对稳定的空间。男主角克拉克曾多次出入其“阈”而毫发无损，直到他组建探险小队，将过多不属于该空间的“人气”带入其中。

随后，“后室”开始向《闪灵》（The Shining）式的恐怖演变。现实中的失败者克拉克，如同杰克·托伦斯，其内心的怨气与空间的滋生相互呼应。他逐渐混淆了自己是噩梦的制造者还是吞噬者，并最终安于这个空间，甚至无视空间对其他无辜者的吞噬——他最终沦为助纣为虐的“伥鬼”。

以上，构成了电影版的基本逻辑框架。

然而，Backrooms最初在网络及YouTube次文化中的诞生，本质上是无逻辑、非逻辑的。其迷人之处，恰恰在于自由阐释的空间、无限繁衍的场景，以及那些微小而诡异的Bug。这种以空间为主角的漫游体验，让人联想到我最爱的日本“暗黑妄想系”动漫：从押井守的《天使之卵》到贰瓶勉的《BLAME！》，再到士郎正宗的《攻壳机动队》（注：原文误写为《仙术超攻壳》），以及更具非理性色彩的逆柱意味。在这些作品中，漫游往往只是作者展开宏大场景衍生的借口，即便有着虚无缥缈的目的，也令人叹为观止。

《BLAME！》作为烧脑神作，以其庞大的篇幅和世界观，描绘了钢窟废墟中无休止的漫游。那些不知属于何年的巨大建筑，让人联想到比利时画家史奇顿（René Magritte，注：原文史奇顿巧构疑为误译或特指某位超现实主义画家，此处保留原意语境）构建的异度空间，但它们源自某种AI悖论导致的建造者失控。

宏大的空间固然震撼（如地球钢窟五千层增生中的失控巴别塔，部分甚至延伸至木星），但更触动人心的是其时间格局。主角二人因遇袭走失，转眼在几页后重逢，女方称“我在这里等了你十年”，令人惘然。后来，为了寻找求救信号，他们乘坐了224,409小时的车——相当于25.6年。故事结尾与开头形成莫比乌斯环般的闭环。

贰瓶勉在此作后创作了《ABAЯA》《人形王国》及近作《塔之迷宫》等宏观迷宫空间作品，但因时间维度的单一，均未达到《BLAME！》的震撼高度。

可见，梦境的哲学化关键在于时间的介入。空间的无限停滞与时间的折叠相遇，最为耐人寻味。

《后室》电影版中最精彩的两个细节正是对此的呼应：
1. 克拉克遇见两名员工早已陷入地面的鞋子；
2. 员工博比滑落下层时，发现大量肮脏衣物，其中一件竟是他之前给克拉克拍片时穿过的T恤。

这与《闪灵》最后一个镜头异曲同工，属于典型的时间折叠，成功在空间迷宫之上笼罩了一层时间迷宫。
