Walking and talking in your sleep are regular occurences for some people, but new research has highlighted that there is a growing trend of some texting whilst they're asleep.
Rising stress levels have been found to be the cause of this bizarre trait.
Experts believe the new phenomenon has been sparked by having too much to do during waking hours.
The rare condition causes sufferers to send incoherent text messages to friends and family, the strange thing is, they're completely unaware that they are doing it.
Smart phones have also been put as part of the blame, as we find it difficult to 'switch off' from our busy, working lives.
Dr David Cunnington, from the Melbourne Sleep Disorder Centre in Australia, says: "We have had patients who have reported sending text messages to their friends and family while asleep.
"It is one of those things that happens but is very rare and certainly not a common trend.
"Because it's so easy to receive emails constantly, and get notifications from smartphones, it becomes more difficult for us to separate our waking and sleep lives."
Dr Cunnington says sleeping with your phone on the bedside table makes it more difficult to get a good night's sleep without feeling obliges to reply to an email or check your Facebook account.
"The key poing is that people need to respect their sleep and make an effort to switch off at night."
