London: Sleep-texting reportedly seems to be the latest fad among today's youth, with increasing numbers of cell phone users text messaging friends while asleep.

Sleep experts said the phenomenon was a natural extension of the younger generation's reliance on modern technology. But scientists disagree on whether it is possible to send a text while technically asleep.

Dr Ron Kramer, of the American Academy of Sleep Medicine said, "Texting for some of the younger generation is probably as ingrained as driving is for some people."

According to Jan Van den Bulck of the Catholic University of Leuven in Belgium, the mobile phone has almost become an extension of many young people's fingers. He claimed to have found similarities between the way typists touch type and keen texters operate.

Jessica Castillo, 24, of Italy, Texas, recently sent two multimedia text messages, apparently after falling asleep during an exchange with her boyfriend.

The first began "Baby u there? Need to tell something..." before it turned into nonsense. To do so, she had to navigate 11 different stages, excluding the typing.
