Is it okay to have so many fictives?

I'm the host of the Tesoro System, and I've just realized we have so, so many fictives.

We have three fictives from Riordanverse books, and two introjects of sorts from the same place. Plus, another fictive from Marvel. I'm not too surprised, since me and two of our other alters are very, v e r y attatched to fiction and often which we were certain characters or in certain worlds to get out of situations. But I'm worried that it's not normal to have so many fictives and introjects. Some of our fictives miss their source material a lot, and I'm worried that the worse things in my life get (everything's going downhill at the moment) the worse it'll be for them and the more likely it is for my brain to decide we need another fictive. I'm scared that having so many fictives will make me loose friends.

What do people think about fictives? Is it normal to have a lot of them?
