孟红在婆婆家里，见到了一个蓝色的纸人。这个纸人仿佛是一个游荡的魂灵，在烛光下活了一般。孟红看到那个纸人的样子越来越清晰，一张隐约熟悉的脸一点一点在眼前变大，孟红潜藏在心底的那个人也铺天盖地地扩大起来，很快和眼前的纸人合为一体。

婆婆说过，那是她们家乡流传的《剪纸歌》。哀怨的曲调，让孟红想起爷爷下葬时，乐师哼唱的歌曲。她不禁鼻子一酸，眼泪流了出来。

“怎么了？”对面的婆婆抬起了头问。孟红摇了摇头，擦了擦眼角的泪。

后来，有个男孩找到了3号楼，他眉目清秀，用温和的声音说道：“你好，我找人。” 孟红依然在说着什么，只是她手里的蓝纸人已经不见了。房间里的灯也亮了，他扶起了她。

病床上的孟 Redsuddenly woke up, looking at 周子全 with a solemn expression. "You have a cat on your shoulder," she said.

周子全 felt a chill run down his spine as he realized that there was indeed something heavy on his shoulder. He had been experiencing strange occurrences ever since the night he hit an unknown object with his bicycle.

The black cat's eyes seemed to pierce through him, its gaze fixed and unblinking. The memory of that night came flooding back, and he recalled hitting something while riding his bicycle under the moonlight.

The cat's eyes seemed to hold an otherworldly power, and 周子全 couldn't shake off the feeling that it was watching him all the time. He tried to push away the memories but they lingered in his mind like a haunting melody.

As if sensing her husband's distress, 孟 Red turned to him with tears streaming down her face. "I see him," she whispered softly into his ear.

Her words sent shivers down their spines as they both realized that whatever entity had taken residence in their home was not just any ordinary presence. It was as if their innermost fears were manifesting themselves in this eerie form.

"Red," 周子 Full gently caressed her hair, trying to calm her down. "It's just your imagination playing tricks on you."

But deep within them both knew that this wasn't just some figment of their imagination; it was real – or at least felt like it – and they could feel its presence lurking around every corner of their lives now more than ever before.

And so they continued living under these strange circumstances where reality blurred into fantasy until one day when everything changed forever...
