( CNN ) -- One of the 12-year-olds charged with stabbing a friend to impress the fictional Internet bogeyman Slenderman was deemed incompetent to stand trial Friday -- at least for now -- according to court documents . After debate between prosecutors and the defense over whether a competency test would violate Morgan Geyser 's rights , the judge asked the girl whether she was competent . `` Court finds the defendant is standing mute , '' court documents show . Dr. Brooke Lundbohm told the Waukesha County , Wisconsin , court that Morgan believes she has mind-control capabilities and can talk to Harry Potter villain Lord Voldemort , according to CNN affiliate WITI . She believes in unicorns , Lundbohm told the court . Morgan also laughed inappropriately and squatted in her chair during her competency review , the doctor said , according to WITI . Another expert , Dr. Kenneth Robbins , said Morgan was n't concerned about a potential long prison sentence , and she said she uses Vulcan mind control , of `` Star Trek '' fame , to feel or believe whatever she wants , WITI reported . Morgan also thinks she can speak to Slenderman and the Teenage Mutant Ninja Turtles , Robbins said , adding that she `` looked happy , almost giddy '' during her exam . While both doctors opined that Morgan was not faking , Lundbohm told the court she could be deemed competent in the future and recommended medication . `` She needs to grow up , '' the doctor said , according to WITI . The judge in the case set a November 12 hearing to discuss the competency report and found `` that the defendant is incompetent to proceed at this time but likely to become competent , '' court documents say . A doctor last month ruled Morgan incompetent , meaning she 's incapable of assisting her attorney in her defense . Morgan and Anissa Weier were arrested in May and charged with luring a pal into a wooded area in Waukesha after a sleepover before stabbing her 19 times , authorities said . The suspects allegedly left the victim to crawl to her own rescue , and a bicyclist found the victim , also 12 , on a sidewalk later in the day . The girls were trying to please Slenderman , a horror story meme the girls had encountered on a website known as Creepypasta Wiki , according to a criminal complaint . One of the suspects told police that Slenderman is the site 's supposed leader , and to climb into his realm , a user must kill someone , the complaint says . Morgan and Anissa are charged as adults with attempted first-degree intentional homicide , and both girls ' attorneys are hoping to have their cases returned to the juvenile court system . CNN 's Amanda Watts , Jason Hanna and Dana Ford contributed to this report .
