可以当作冷战时期的政治隐喻片(共产主义/麦卡锡主义),也可以当成科幻恐怖片(尤其最后有《釜山行》的感觉)

其他解读思路/角度:

1. Double-Uncanny-Identity Issue-Social Context (fear of losing individuality; warning of the invasion of communism in the 1950s: “you’re the next one!”);

2. “People not believing”(ideology & fear)- the outbreak of pandemic (柏拉图洞穴的寓言, 见到光明的人返回洞穴无人相信);

3. “Everyone is suspicious”(ideology & fear-even your closest ones changes immediately)-cultural revolution/fascism (where the society longing for unity/everyone feeling good in the group);

4. 爱与痛-what makes a human human, 是人生意义的永恒主题;

5. reality-dream and reality;

6. identity issue- body/mind continuity
