Heaving somebody besides you who carry out a conversation in their sleep can be a freakish experience.
Now the latest study suggests that sleep talkers often utter profanities and abuses during night time conflicts in dreams and it has also found an unusual quality being grammatically correct among them.
The study that was published in the journal Sleep, analysed sleep-associated speech in 232 adults and the researchers found that sleep-talkers follow the patterns of a typical conversation and even took pauses to let the other person speak their part.
It was also revealed that men abused more in their sleep as compared to women and the most commonly uttered word in their speech was 'No'.
"Sleep-talking may correspond to the “punch-line” of a conversation, the emergent, most violent part of the iceberg of covert speech, increasing the negativity of the language and verbal abuse", researchers stated in the study.
The French study also stated that the participants may not curse as much when they awake, but the rate was found to be 800 times higher when they were sleep talking.
The study is believed to be one of the largest probes into sleep-talking. It has helped to provide new insight on this phenomenon and the findings have challenged long-held beliefs that sleep-talkers become child-like during episodes.
