My Roommate Always Combs His Hair in the Middle of the Night

My roommate who sleeps across from me always combs his hair on my bed in the middle of the night. Once, twice, three times... Finally one day, she stopped combing her hair. But I found that her belly was getting bigger and bigger. When I told my best friend about this novel discovery, her tone suddenly became nervous. "I saw a ghost while combing my hair in the middle of the night! She is pregnant with a ghost!" "Be careful, your roommate is going to harm you!"
