¿Quién hay ahí?

The story's claustrophobic environment really amps up the suspense. I wonder if Campbell drew from real experiences or invented it all from imagination.

As paranoia took hold, I kept questioning who was truthful or hiding something. It made me think about how fear influences our perceptions.

The mysterious nature of the alien adds to the suspense, but I wonder if Campbell wanted to explore fears of the unknown or something else.
