Human?

Being careful not to make any noticeable movements, Alex carried on eating his food as if he had heard nothing, but he was much more alert than beforehand.

Mira was no different. She had heard the same thing, except for the fact she was facing the direction the sound came from.

It was hard to tell in the darkness, but she swore she could make out three dark silhouettes before they disappeared.

Since Alex was facing Mira, away from where the sound came from, he mouthed to her, acting like he was chewing on some meat.

'Something in the darkness?'

Mira fake yawned and tilted her head up and down in the process.

This was a clear 'yes' to Alex's question.

Fwoosh

All of a sudden, something came flying out of the darkness and brushed past Mira's face, her barely dodging in time.
