Samo da razjasnim ovo nema nikakve veze sa poremećajem ličnosti ovo je romantiziranje psihičkih poremećaja potaknuto tumblrom.
Nisam našao prijevod na hrvatski tako da moje isprike onima koji ne znaju engleski.

Headmates
An alternate personality or identity living in your head. Similar to a roommate or a house mate, but inside your skull. A person who describes themselves as having headmates is saying that they have people living in their heads who they have conversations with.

Some people can claim different ethnicities or sexualities, thus allowing them to join an autonomous caucus (for instance queer or women’s) that they were not otherwise entitled to join.

When they are acting as the personality of one of their headmates, they call this "fronting"

Kakav je vaš stav prema ovakvim ljudima, mislite li da je to stvarno ili samo privlačenje pažnje?
