Answer:
The mere fact that something is atypical or odd does not imply that it is disordered. A person may have atypical interior experiences or display unusual behaviors, but she is not labeled disordered if these sensations or behaviors are not distressing, disturbing, or suggest a dysfunction. A classmate, for example, may stay up all night studying before examinations; while unusual, this behavior is unlikely to meet any of the other criteria for psychological condition outlined above.
