Does my friend have sleep paralysis ?

Sleep issues: witout a definitive sleep study its not possible to make the diagnosis

Any other info?: If your friend wakes up in the morning and finds that (s)he is unable to move for a few moments and then suddenly movement is restored, then, yes your friend could have sleep paralysis. Usually this can be diagnosed by history and does not in-and-of itself require a sleep study. If caused by something like sleep apnea, this would require a sleep study to diagnose.
