I don't see any benefits of dissociation. Pursuing your issues, like fear of having someone take care of you, is a good route to take but avoiding dissociation is also good. This is why therapists try to bring you back and ground you when you dissociate.

I have a few ideas about your fear of having someone take care of you (if you want to think more deeply on this) but since you didn't ask to get info on that I won't say anything unless you ask.
