Night of Suffocation

On a sultry summer night, when I looked up by chance, I saw an incomprehensible horror outside the fourth-floor window. It disappeared quietly, but the network was strangely intermittent. When sporadic similar witness reports flashed on the edge of the disconnected network, the protagonist was shocked to realize that that night was not an illusion, but the prelude to the arrival of some kind of "existence". Silence is spreading unstoppably, and the familiar world is beginning to fade silently from the edge.
