"Claire, are you okay?" Seeing that her friend had a tense expression as she looked ahead, Sasha asked.
Claire heard the question, but she didn't answer right away. She didn't mean to be rude or ignore Sasha on purpose, but her attention was too focused on the strange pressure she was feeling coming from the haze they were heading toward.
Maybe pressure wasn't the right way to describe the feeling that seemed to be transmitted directly to Claire's mind, but she had no other way to call it. Seconds passed, but she remained unable to determine the cause of her discomfort, so her concentration ended up receding.
"Don't you feel anything coming from the fog?" Claire asked, trying to see if she was the only one having the strange feeling.
